Here I am, 1 year after I posted below, still using your video on removing the printhead. After removing the printhead, and giving it a good cleaning in lukewarm water, and re-installing it, it printed again up to this point. But, now, I forgot how I did it so I am glad this video is still up so I can do it again. Thank you again, very much.
This video and another one from another guy helps me from buying another printer which would cost at least $150. I used this video to open and clean the printhead first but it didn't work. So I ordered a printhead and replaced it. I made a mistake first time that it didn't work . I reopened it again and reinstalled and it then works! I paid $32 for the new new printhead. My printer is HP 6978. Thanks
I've been in printers over 20 (OK 25 yrs) & never knew they were this much to disassemble. No wonder it's cheaper to buy a new one vs repair, when labor is $35-50 /hr. Shop repair vs Big Box. Great video. (I know, newer cartridges are smaller so they recap their costs faster. I remember every few days, some Canon's print test page to keep lines fresh.)
Great video. Took everything apart and got the printhead out. Once out, I used 70% rubbing alcohol to clean / soak the print head and remove all of the ink inside. Took about 30 minutes or rinsing / pouring. Then I blew with compressed air and let dry overnight. Put back together the next day and printer works fine. I also cleaned out the messy area where you will find lots of old ink that looks like grease. Once printer was disassembled, I took printer outside and put on its side so water would run out as I cleaned it. The electronic board was on top so as to avoid getting wet. Then I took a waterpik and rinsed the entire area, Caution - used ink goes everywhere. There is a small sled that moves to the front to cover the printhead when the printer is turned off. I made sure that those rubber pieces were clean. Blew with compressed air and let sit overnight to dry. Difficult areas. 1. When you put the scanner cover back on the back right has to be slotted into the glass plate cover before you put the piece back in. 2. The plastic guide bar for the printer head. The dot and the arrow go on the right side, arrow facing back. Must do the left side first, then feed the ribbon through the print head to the other side. Then compress spring on left side to get over the hook on the right. Can go the other way since the left side has barbs on it. 3. Front LCD cover plate. It removes from the top right first. Then press the tab on the bottom left as you pull and rotate counter clockwise. Installation the same way. Bottom left first, the rotate clockwise and it should snap back in. I have a second printer that I will clean next week and try to post photos.
@@happykrafter5756 you're right, I spent 5 minutes fiddling with the L side and that was after pressing that tang from below. But I did not also lift the top bezel as he did in video. That might be a good trick to include.
THANK YOU so much for making this video! Yes, a $50 printhead was far cheaper than the $200 printer! I really like my printer, and thought it would be such a waste to toss, but thanks to you it's working!👍
This is gold! Thank you so much. My printer head is stuck in one corner and no amount of effort is working. I saw all kinds of HP support videos etc. Now Ima try it your way. Ripping apart will be fun!
I am currently having the same issue. This video is VERY helpful. My carriage is however still stuck and stuck on the right side. Any pointers on anything else to remove?
Thanks man! Pulled the printhead and flushed it out good with contact cleaner from the printhead side, and now it works great! I had tried just flushing from the ink supply side but it didn't print very well, then got fully clogged the second time I flushed it.
Thanks for the video. I found the problem that may have caused many others to trash their printers. It was a broken plastic gear on the print head slide bar. The next step is to find the gear!
Thank you very much for this video! My sorrowful HP6950 will leave me now, but I wanted to keep the printhead and some other parts, because we have more printers of this kind. BTW, clogged printheads can be cleaned with brush cleaner liquid (any paint solving liquid will do, but not Acetone!). Then, rinse with printhead liquid (or water/ethanol 50/50), then rinse with either printhead liquid / ink 50/50, then re-insert cartidges.
Just the information I needed to remove printhead.. need a source to purchase a new one.. good tip to take pictures as you go.. I would forget how things were in minutes
Very informative video for me when I need to fix my printer. Generally I found most of my HP printers are out of order because the rubber parts/rollers no more soft to grip paper cause jams after 4-6 years later.
Great video on my HP 6978 printer. I am getting a 0xc19a0035 error, I tried to clean the print head while in the printer, but still no luck. I am thinking that a new printer might be my best efforts.
Thank You for the video, before I watched this video, I took my HP6962 printer apart for cleaning because I was getting a false error code for a paper jam, my printer looked to be in good condition, I cleaned it, rollers, print head, put it all back together and I'm still getting an error message, I'm frustrated after taking it apart twice, and still getting paper jam message, do you have any advice to find out what is causing this? also the gears look good, none stripped, or cracked.
There was a couple spots where further description would be helpful. For example, the angle for pulling the hook to detach it from the scanner. The angle for pulling off the screen to not break the internal clips. I would also like to know how to access the ink waste reservoir. Can you replace the reservoir for this printer? I haven't seen any videos on it yet. My next question, I accidentally placed the wrong ink within the cartridges. My printer still worked but cyan was plugged up (hence why I had to take the print head out). I refilled the cartridges with the new ink that is supposed to be compatible with the printer. Should I replace the cartridges? Or simply drain the cartridges of the old ink and add in the new?
Hello. Thank you for the remarks. Regarding ink, it is probably best to replace the cartridges. If you want to keep using it, you will have to flush it with distilled water many times. I haven't reppace ink waste tank on this printer. I have a similar printer for a project and if I'm able to replace ink waste tank, I will post a video.
Hi thank you very much for showing how to safely remove the parts. I have a problem and I would be grateful if you could give me your opinion. I have the HP 6950 model which I assume is almost the same on the inside. My problem is that the it doesn't print any black colour. The inks are genuine and new from HP Instant Ink. I did all the automatic cleaning tasks the printers offers but nothing happened. I searched all over the web and read about cleaning the printhead. I used a damp cloth that absorbed the residue and then I used cleaning liquid inside each silver printhead hole. I even used an air-compressor to remove all the clogged colour left inside. Even though the other colours are printing properly as they did before, the black is still not printing even after the cleaning I performed. Do you think that removing the printhead and cleaning it out of the printer would give any positive outcome? Do you suggest replacing the printhead? Do you have any cleaning tips? Any help would be very much appreciated because I am out warranty and it may not worth sending the printer for repair. Thanks.
Hi. I apologize for delayed response. It is possible that black nozzle is clogged badly or is "fried". Usually when one of the nozzles fails electronically, the printhead error pops up, so I think you may need to pull the printhead out and do some manual soaking and cleaning. And you are sure the cartridge is good, right?
@@303electronics Hi and thanks for the reply. There is no error at all coming from the printer. It just keeps "printing" as normal but there is no black colour. The cartridges are brand new genuine from Instant Ink. I noticed that this started happening before the brand new cartridges. However I assumed because the ink level of the previous black one was very low I thought that it was over. I found a genuine spare part HP Printhead for HP 6950 on Amazon for about 60€ but the same printer now sells for 90€ if you buy it new from a computer shop. I am in a dilemma - The printer lasted for 3 years and in total I had printed about 750 pages. It's disappointing.
Because you tried to help, I just wanted to update you on my complete tear down of my HP 6968 with the stuck carriage to the right. There were no cracked gears found anywhere. No physical explanation could be found for the problem. I suspect the optical reader that controls the movement of the problematic sled down below, was not reading accurately thus causing the sled to stop prematurely. That little 1 inch square PC board sitting on top at the right end controls the sled's Optical Reader directly beneath it. Since it would complete one cycle perfectly then malfunction on the second cycle, I suspect the programing on that PC board became corrupt. I think my printer is non-repairable! Thanks again.
Hi. It does not have a hard drive. The printer memory is just enough to process jobs and store main function operations. You can try resetting the printer, but if you still want to make sure you're safe, just remove the main printer board and break it. 😉
Helpful video for taking apart the printer, thank you. I'm getting an error code, 0x610004a, on my 2-year-old 6968 model. This is apparently due to an ink catching "tray" that sits on the bottom right of the unit under the ink cartridge carriage. The tray is not dropping down properly to allow the carriage to move freely and print. I can use a screwdriver to turn the small plastic cogs on the right of the carriage bar which moves that tray towards the back of the unit and out of the way so the carriage is free to move, but as soon as I power the unit back on, it resets, the carriage goes back to its "resting" spot, gets held up and that error code reappears. Any suggestions for repairing this would be appreciated. Was a good printer up until this point. Worthless at the moment. HP support was of no help, all they wanted to do was take all my contact info, (to resell I'm sure), and try to sell me a "discounted" printer. Thank you.
@@tobifasola2017 Unfortunately, no. I ended up buying a used printer on Facebook Marketplace that so far has been working fine. I donated the 6968 to an organization in Cleveland that teaches young adults how to take apart and repair computers and peripherals. Figured if nothing else, it could be a teaching tool for some students.

Yeah this is spot on. I think this is the problem where most of these "paper jam" issues come from. I just took apart my 6962 and that tray is overflowing with messy ink and it won't move backward as it's supposed to. I don''t think it's a salvageable operation unless you're willing to get really messy and replace a bunch of tiny parts
What size hex for removal of the. 10 screws holding the top portion.of the main portion of the HP - mine is HP6978 and has a very small HEX top/slot on each of the 10 screws.
Okay so the print head is out , the carrier unit is out.... am I just supposed to clean it all and reassemble? it’s quite caked with black ink...The head was jammed but there is no broken parts, I’m not sure what the problem is that I’m having.... is there any advice you can give(something to watch for in that area?) thank you for this vid!
Thanks for this comprehensive video! I'm trying to fix an issue where the ink carriage is stuck and I believe there is a part that is blocking it. The printer is only three months old and it's hard to believe something as simple as unplugging it while it's operating could brick it. Do you have any advice for this issue?
I have the same issue. I forgot to turn off the printer and we had a power outage from a storm now the carriage is stuck. If you found a simple solution let me know. I tried to remove the first cover but could not get the screen to come off. I cannot figure out why the carriage is stuck.
@@seeker1970 Hey Will, nothing yet. I took it apart almost completely and can't manage to move the ink carriage. There's something underneath it that isn't letting it go back down and because of that it will not move down the track. I got the squaretrade warranty at Target when I purchased it and am going through the process to get it replaced now. Sorry I couldn't be more help!
@@seeker1970 Good news actually! I managed to fix it! An HP rep had me unplug everything and then hold down the power button for ten seconds. He said this drains the printer of any power completely. When I plugged it back in it printed a test page perfectly fine. Give this a try and I hope it helps!
@@ShinyShandera Thanks for the tip but it did not work for me. I might try one more time to take it apart...with a hammer. I think this is the last HP printer I purchase. I'm going to try another brand. One with less expensive ink cartridges.
Excellent How-to video! Thank you. Please do one for how to fix HP 6968 carriage hangs up on the right triggering false paper jam error. Goes thru initialization cycle with no problem until it reaches the very end where attempts to move carriage to the left for printing but can't because it gets hung up on the ink catch basin underneath that does not fully retract out of the way. And thanks again!
@@303electronics I am having the same problem; printer carriage will not slide to the left as it is caught on the catch basin under it. At 10:57 the video mentions that something is slid back to release the carriage, but I cannot see what was done and have not been able to free up the carriage even though I have it disassembled to that point. A bit more explanation would be GREAT!
Thank you thank you thank you, I'm going to remove the printhead for cleaning even though I could do that while it's installed but I don't think I could do it properly without removing it.
Thank you so much for this! I had to clean my printhead as my printer was not printing black. However, after putting it all back together, now my cartridge is stuck on the right. I manually turn the wheels to move the bottom part of the printhead up and can then move the printhead around. The printer then just cycles it back and the cartridge gets stuck again... Any recommendation on how I can fix this issue? I have the 6968
Hi, Very useful video, thanks. I have managed to remove the top cover to get at the print head which I aim to replace. I have ordered a new print head from ebay (Chinese supplier) for £29.50. Says it is compatible so crossing my fingers I can breath new life into my HP Officejet Pro 6960.

Thanks for sharing this video @303 Electronics, I feel more confident in taking apart this very printer I have due to no black ink printing out from my new cartridges. I even bought the recommended cleaner you showed in another video. I do have one question though. When I open the printer top head to reveal the printer head with cartridges and once it moves to the middle position so that I can remove the cartridges, I notice that to the far right (where the printer head stays in default home spot) that there is a puddle of black ink on the ribbon connection and on the bottom of that area. Almost as if ink spilled in there. Is that normal? Thanks in advance.
Oh ok. So it's grease? Yeah I noticed it had some type of white pad underneath it. So I wanted to make sure before I did anything just in case there was a reason for it being that way. But I can definitely tell that ink splattered around that area too.
Thanks for posting such a thorough video. I have a 6968 and the black nozzles of the printhead were thoroughly clogged. I've unclogged many hp printheads, but this was a first 6900 series and I was able to follow your instructions to remove the printhead which I cleaned and reinstalled, but the problem I'm having is the the carriage is now slamming all the way to the right HARD. Then it tries to push farther right before rifling back left and getting stuck 1/2 way producing a carriage error. I did not remove the encoder strip like you did in the video. I left it in place. The nozzle was clogged before disassembly but the carriage moved fine without issues. Is it possible I damaged the encoder strip or maybe didn't align it with the carriage properly?
I'm having the same issue as stated After cleaning the timing strip and shaking vigorouly it started to print a test page before sucking up a bedsheet oh my same thing again Did anyone fix this carrige jam issue
I’m sorry, but these instructions are wonderful. You broke your printer yourSELF. Perhaps you have never tech’d an hp printer before. I don’t know; I only know that you are an angry, rude person.
Carriage removal is much easier with one screw loosened at 11:11. Then the tensioner will move to allow belt to grow and get over the rim of pulley. You're trying to move the tensioner here, but it won't without being loosened. TIME POINTS for review to reassemble: 12:12 carriage 10:10 carriage rod 11:55 print head wiring 5:45 print head springs point outwards 7:20 print head 7:55 circuit board 9:03 rear port covers 2:55 touch screen

Product: Hp Office Jet 7612 I have a HP OfficeJet 7612 turned it on carriage jam came up so I inspected for anything in the way to keep the carriage from being able to move and found what was blocking it in is a flat plastic piece, which looks like a small clip on cover, so I removed it and the printer is working but I am a bit worried about re-fixing this piece back on. The number on the back of the piece is: CR769-40117 >PS-HI< H4 Can you advise please?

Looking at the front of machine, in the right hand corner, under roller bar there is a unit that appears to move back and forward .. it is covered with what looks like excess ink. Suggestions on how to clean and/or remove. What is this part called?
Hi. I think you are talking about ink gunk which builds up from excess ink over a long period of use. I suggest removing the hardened gunk with a q tip or any small stick. I use a plastic knife or a screw driver.
My paper is jamming on my 6978 as it is about to spit it out. I see that a little spring is off on the roller beneath the ink printer heads. There are 5 double steel little cog wheels just below the ink track and it the one on the right that has the spring slipped off. How difficult is it to fix and reattach that spring?
Hi, thanks for your great video. I still have a problem to take out the carriage. In your video you don't show clearly the way to take it off to be able to move it to the middle, as it is stuck on the right side. Could you clarify this parr or send me a little video for this part? Thanks in advance! Martin
Hi. There is a mechanism under the ink carriage thtvslide back and forth. Gently push it back with a screwdriver. That will release the carriage and it will slide freely.
Ohhhhh... I now see the tray release buttons are 'underneath' my 6958; my old HP release buttons were visible in front....😀 and easily released with my fingertips. -** 6958 sure makes it 'harder' to remove that tray to look for paper jam.....
Thanks a lot for this video! Very sorry for having so mention this, but I still need help. So if anyone knows how to solceproblems with forwarding paper please let me know! Printer 6960 accepts paper. But the forwarding always stops wenn the paper is in the back on its way half through turing over the rolls. I can remove it easily and completely and I did not find any little piece of paper left in there. It did print once printerinformation. After that no sheet came through to do a proper printint. It always says paper jam. I need help, please.
I have an office jet pro 6970 that I replaced the black ink after a warning indicating it would need replacing. After replacing only the black ink cartridge the printer stopped printing black. Even after many attempts to clean the print head from the menu, the other colors would print on the test paper but not the black. I also tried to print a copy of page and the paper was blank. I followed the recommendations on the HP site and unplugged the printer from the power outlet for at least 60 seconds and that did not work either. Manually cleaning the printhead with alcohol did not work either and I repeated the process many times. I have come across an article saying there is a hardware circuit that stops the black from printing but it did not give any details or information how to resolve that problem. I was contemplating the idea of buying a replacement printhead and installing it myself but not sure if that would make a difference.

Thanks for sharing! I got to the point when you release the carriage so it can slide to the left (10:56) but the video doesn't show where exactly you release it...can you please provide some guidance? Thanks!
I just moved back the "carriage lock mechanism" that is located under the carriage. You can move it with a screw driver by pushing it back. You can have it unlocked by opening the cartridge door and unplugging the printer. The carriage releases after you remove the clamps on both sides of the rod and release the driver belt. Please let me know if this was what you needed or if I didn't explain it.
@@303electronics Thanks for replying! The failure I have with the printer is that the carriage is stuck on the right (slightly moves to the left but no more). So it can't slide to the middle as happens when you're replacing the ink cartridges...Not sure where is exactly the carriage lock mechanism.
I sent you a photo of the carriage in my printer through a message on your FB page, if you can mark the lock mechanism on the image and send it back it'll be very helpful. Thanks!
First, thanks for some great videos, explaining things clearly in plain english & a lot of patience!! I'm having a somewhat similar problem with a 6978. I keep getting 'paper jam'' error even after clearing the paper path & checking it multiple times & the printhead is frozen to the right & will not budge. I've tried powering off & on multiple times. It actually started with a tree limb falling across a power wire somewhere. Power was lost quickly & apparently cleanly & was restored in a similar manor. The printer was idle & plugged into a power protection outlet. I have contacted the electric company with no help. I have not contacted the outlet company yet. I am comfortable with a V-O-M meter good with a soldering iron, so any voltage checks would also be appreciated. My only problem is that I'm 72 yrs old & not as good as I once was & have a very limited supply of cash or I would just replace it!! Sincerely, Ed Hellwig efhlith@gmail.com (330) 347-2246 ( voice & text) Any help would be greatly appreciated

Hi. The problem is that the clear strip in the bavk of the printhead needs to be in that sensor area. Make sure it is dry there too. The timing strip is on about 3 millimeters in width and is attached from one side of the printer to the other. It controls the carriage when printing. Since you removed printhead, you misplaced the strip. It just needs to be repositioned inside of the sensor. Let me know if you were able to figure that out. Thanks.

I replaced the printhead exactly as shown via this excellent video. Still only prints blank pages. Put in new ink, updated firmware, calibrated and all that. I think these printers are garbage and designed to fail. They are a serious waste of plastic and resources. I’ll never buy one again.
My scanner that scans the flatbed was stuck and wasn’t going across the glass below. However the scanning documents from the Documents Automatic Feeder still scans ok. How do you take apart the scanner bed to unstick the light bar? You didn’t show that on the video.
Hi. When you remove that assembly that has the scanner bar, flip it over and there will be about 8 screws around the perimeter. Remove those with a t10 screw tip and unclip the top portion from the bottom. Be careful to not let the inside parts fly out.

I have this exact printer, and I'm here because it seems my yellow has gotten clogged, so I'm looking for a solution. When my HP Officejet Pro 6978 works as it should, it outputs great quality prints and does so pretty quickly. However, when I haven't printed something in over a week, it seems it always has to wake up and go through this lengthy maintenance process before it actually starts printing what I need, which is pretty tedious to say the least. With that said, I would HIGHLY recommend against purchasing this printer or any HP printer based on this platform design. First off, the ink cartridges are among the most expensive on the market. For a set of genuine HP 902XL cartridges, (XL meaning the larger ones that hold more ink) you're looking at right around $100, and even on Amazon or Walmart a full set runs around $100. Then there's the fact that this printer absolutely BURNS through ink like a fighter jet through fuel. I don't think I've ever gotten more than 50 or so pages from a single XL black cartridge. We do only occasional printing in my home, never for any sort of business purposes, and mostly for stuff like an occasional picture our son has drawn, and maybe a couple dozen pages of text documents a month for doctors visits or food recipes. At best a set of these cartridges lasts us maybe 3 or 4 months. We easily go through $300 in cartridges a year in the four years we've owned this printer. I've lost track of how many times I've uttered the phrase "WTF, I swear I just replaced these cartridges!!!"
Agree! I fixed my printing problem but then I remembered how expensive the ink cartridges are! For what I've spent on ink, I could've bought a few brand new printers! I'm looking into a tank printer where you literally fill it with cheap liquid ink when you need to and it lasts a long long time.
Try to remove printhead and clean the contact area. Since it has been sitting in storage for awhile some ink may have spilled on the side and is interfering with the contacts between prinhead and carrier.

I have this printer and it stopped printing black ink. Like, zero output. Ran clean print head about 30 times this week, nada. New cartridge, genuine HP from Staples, nada. Tried pushing alcohol through the head and used compressed air to clear as much as possible, nada. This lead me to your video. Took print head out and brushed with denatured alcohol and a toothbrush, then wiped with microfiber, nada. Any ideas at all? I'm going crazy.
Removed the printhead on hp 6962 to clean it. Then replace the printhead. Now get a code on screen saying problem with printhead. Any way to fix this problem?
I did the same thing, I am curious if it has to do with the encoder timing belt? If there is a wrong way to put that back or not.. I tried flipping it upside down also... still nothing... Printer gives me one or more cartridges are missing or damaged error, yet never did before until after I took apart to run water through the print heads

Here I am, 1 year after I posted below, still using your video on removing the printhead. After removing the printhead, and giving it a good cleaning in lukewarm water, and re-installing it, it printed again up to this point. But, now, I forgot how I did it so I am glad this video is still up so I can do it again. Thank you again, very much.
This video and another one from another guy helps me from buying another printer which would cost at least $150. I used this video to open and clean the printhead first but it didn't work. So I ordered a printhead and replaced it. I made a mistake first time that it didn't work . I reopened it again and reinstalled and it then works! I paid $32 for the new new printhead. My printer is HP 6978. Thanks
I'm glad you got it fixed! Thank you very much for sharing! Have a great weekend!
I've been in printers over 20 (OK 25 yrs) & never knew they were this much to disassemble. No wonder it's cheaper to buy a new one vs repair, when labor is $35-50 /hr. Shop repair vs Big Box. Great video. (I know, newer cartridges are smaller so they recap their costs faster. I remember every few days, some Canon's print test page to keep lines fresh.)
Great point! Thank you for sharing! Have a great day!
Great video. Took everything apart and got the printhead out. Once out, I used 70% rubbing alcohol to clean / soak the print head and remove all of the ink inside. Took about 30 minutes or rinsing / pouring. Then I blew with compressed air and let dry overnight. Put back together the next day and printer works fine.
I also cleaned out the messy area where you will find lots of old ink that looks like grease. Once printer was disassembled, I took printer outside and put on its side so water would run out as I cleaned it. The electronic board was on top so as to avoid getting wet. Then I took a waterpik and rinsed the entire area, Caution - used ink goes everywhere. There is a small sled that moves to the front to cover the printhead when the printer is turned off. I made sure that those rubber pieces were clean. Blew with compressed air and let sit overnight to dry.
Difficult areas.
1. When you put the scanner cover back on the back right has to be slotted into the glass plate cover before you put the piece back in.
2. The plastic guide bar for the printer head. The dot and the arrow go on the right side, arrow facing back. Must do the left side first, then feed the ribbon through the print head to the other side. Then compress spring on left side to get over the hook on the right. Can go the other way since the left side has barbs on it.
3. Front LCD cover plate. It removes from the top right first. Then press the tab on the bottom left as you pull and rotate counter clockwise. Installation the same way. Bottom left first, the rotate clockwise and it should snap back in.
I have a second printer that I will clean next week and try to post photos.
Thank you very much for sharing your experience. It is very helpful and interesting. Have a great day! Looking forward to your updates!
#3 is much easier said than done.
@@happykrafter5756 you're right, I spent 5 minutes fiddling with the L side and that was after pressing that tang from below. But I did not also lift the top bezel as he did in video. That might be a good trick to include.
@danielradulski2911 might need to fix that last sentence on #2. Can't? ... or can, but then the plastic "ribbon" won't ... unsure the point
THANK YOU so much for making this video! Yes, a $50 printhead was far cheaper than the $200 printer! I really like my printer, and thought it would be such a waste to toss, but thanks to you it's working!👍
Great! I'm very glad you were able to fix it and made it work again! That was the idea! Thank you so much for sharing!
where did you get the printhead replacement?
AliExpress
AliExpress was where I got it@@JoseAlbertoDiaz
Further to my comment below, I have now replaced the print head and the printer works perfectly. Thanks again for the detailed video
Great! Thanks for the update! Have a great weekend!
Thanks for your video, it allowed me to dismantle the print heads to clean the blue head that was blocked. Now everything works fine on my 6960. ++
Thanks for the interesting video.
How did you manage to remove the screen?
This is gold! Thank you so much. My printer head is stuck in one corner and no amount of effort is working. I saw all kinds of HP support videos etc. Now Ima try it your way. Ripping apart will be fun!
Thanks. Good luck!
Did you ever fix your problem? Mine is having the same issue I think.
I am currently having the same issue. This video is VERY helpful. My carriage is however still stuck and stuck on the right side. Any pointers on anything else to remove?
Thanks man! Pulled the printhead and flushed it out good with contact cleaner from the printhead side, and now it works great! I had tried just flushing from the ink supply side but it didn't print very well, then got fully clogged the second time I flushed it.
Thanks for the video. I found the problem that may have caused many others to trash their printers. It was a broken plastic gear on the print head slide bar. The next step is to find the gear!
I found a broken plastic gear inside my 6975 printer. Did you find a replacement?
@@RandomCasualOrdinary I have this issue as well, any word on a replacement?
@@ieatmygarden same problem here, I think. Are we talking about a small white plastic circle?
Awesome video fixed my mom’s printer! Saved us a lot of money because she was ready to trash it!❤
Great video, thanks! Unfortunately, it only convinced me to buy a new one...
Thanks for the feedback. Have a great day!
Thank you very much for this video! My sorrowful HP6950 will leave me now, but I wanted to keep the printhead and some other parts, because we have more printers of this kind. BTW, clogged printheads can be cleaned with brush cleaner liquid (any paint solving liquid will do, but not Acetone!). Then, rinse with printhead liquid (or water/ethanol 50/50), then rinse with either printhead liquid / ink 50/50, then re-insert cartidges.
Thank you for sharing!
Did you have to take the print head contraption out to clean the printheads with that solution. My blue ink is woefully clogged.
Just the information I needed to remove printhead.. need a source to purchase a new one.. good tip to take pictures as you go.. I would forget how things were in minutes
Thanks for this video. New print head ordered and installed. Far cheaper than a new printer.
Great! Thanks for sharing.
Very informative video for me when I need to fix my printer. Generally I found most of my HP printers are out of order because the rubber parts/rollers no more soft to grip paper cause jams after 4-6 years later.
Thank you for sharing! Have a great day!
Great video on my HP 6978 printer. I am getting a 0xc19a0035 error, I tried to clean the print head while in the printer, but still no luck. I am thinking that a new printer might be my best efforts.
I have 6968 and it looks exactly same! Thank you so much for the vid! I need to fix black ink clog with this
I actually needed instructions for a Pro 6968 but this video still helped. Thanks!
I'm not sure what it is that you repaired. But I did learn in what order to take printer apart. Thanks.
Thanks for your video! I was crazy looking for videos about the replace of output tray in HP6970.
And I did it!!
Thank you so much for the feedback and I'm glad you found our video. Have a great weekend!
Thank You for the video, before I watched this video, I took my HP6962 printer apart for cleaning because I was getting a false error code for a paper jam, my printer looked to be in good condition, I cleaned it, rollers, print head, put it all back together and I'm still getting an error message, I'm frustrated after taking it apart twice, and still getting paper jam message, do you have any advice to find out what is causing this? also the gears look good, none stripped, or cracked.
Thanks a lot. This video helps to fix my HP6975 printer head carriage problem.
There was a couple spots where further description would be helpful. For example, the angle for pulling the hook to detach it from the scanner. The angle for pulling off the screen to not break the internal clips. I would also like to know how to access the ink waste reservoir. Can you replace the reservoir for this printer? I haven't seen any videos on it yet. My next question, I accidentally placed the wrong ink within the cartridges. My printer still worked but cyan was plugged up (hence why I had to take the print head out). I refilled the cartridges with the new ink that is supposed to be compatible with the printer. Should I replace the cartridges? Or simply drain the cartridges of the old ink and add in the new?
Hello. Thank you for the remarks. Regarding ink, it is probably best to replace the cartridges. If you want to keep using it, you will have to flush it with distilled water many times. I haven't reppace ink waste tank on this printer. I have a similar printer for a project and if I'm able to replace ink waste tank, I will post a video.
Thanks for the video! Just replaced a defective print head in one with your simple steps.
Hi thank you very much for showing how to safely remove the parts. I have a problem and I would be grateful if you could give me your opinion. I have the HP 6950 model which I assume is almost the same on the inside. My problem is that the it doesn't print any black colour. The inks are genuine and new from HP Instant Ink. I did all the automatic cleaning tasks the printers offers but nothing happened. I searched all over the web and read about cleaning the printhead. I used a damp cloth that absorbed the residue and then I used cleaning liquid inside each silver printhead hole. I even used an air-compressor to remove all the clogged colour left inside. Even though the other colours are printing properly as they did before, the black is still not printing even after the cleaning I performed. Do you think that removing the printhead and cleaning it out of the printer would give any positive outcome? Do you suggest replacing the printhead? Do you have any cleaning tips? Any help would be very much appreciated because I am out warranty and it may not worth sending the printer for repair. Thanks.
Hi. I apologize for delayed response. It is possible that black nozzle is clogged badly or is "fried". Usually when one of the nozzles fails electronically, the printhead error pops up, so I think you may need to pull the printhead out and do some manual soaking and cleaning. And you are sure the cartridge is good, right?
@@303electronics Hi and thanks for the reply. There is no error at all coming from the printer. It just keeps "printing" as normal but there is no black colour. The cartridges are brand new genuine from Instant Ink. I noticed that this started happening before the brand new cartridges. However I assumed because the ink level of the previous black one was very low I thought that it was over. I found a genuine spare part HP Printhead for HP 6950 on Amazon for about 60€ but the same printer now sells for 90€ if you buy it new from a computer shop. I am in a dilemma - The printer lasted for 3 years and in total I had printed about 750 pages. It's disappointing.
Because you tried to help, I just wanted to update you on my complete tear down of my HP 6968 with the stuck carriage to the right. There were no cracked gears found anywhere. No physical explanation could be found for the problem. I suspect the optical reader that controls the movement of the problematic sled down below, was not reading accurately thus causing the sled to stop prematurely. That little 1 inch square PC board sitting on top at the right end controls the sled's Optical Reader directly beneath it. Since it would complete one cycle perfectly then malfunction on the second cycle, I suspect the programing on that PC board became corrupt. I think my printer is non-repairable! Thanks again.
I'm sorry for the outcome. Thank you very much for the update!
Does this printer have a hard drive and how do you remove it ? thanks for this video , it's my exact printer .
Hi. It does not have a hard drive. The printer memory is just enough to process jobs and store main function operations. You can try resetting the printer, but if you still want to make sure you're safe, just remove the main printer board and break it. 😉
Thank you .@@303electronics
Nice video. I have to ask. The fax component is mounted on the control board?
thank you so much this was awesome i would not have been able to figure out how to get the top scanner part this helped so much
Thanks. Have a great evening!
Finally I found the correct video. Thanks for the help!
You're welcome! Have a great day!
Helpful video for taking apart the printer, thank you. I'm getting an error code, 0x610004a, on my 2-year-old 6968 model. This is apparently due to an ink catching "tray" that sits on the bottom right of the unit under the ink cartridge carriage. The tray is not dropping down properly to allow the carriage to move freely and print. I can use a screwdriver to turn the small plastic cogs on the right of the carriage bar which moves that tray towards the back of the unit and out of the way so the carriage is free to move, but as soon as I power the unit back on, it resets, the carriage goes back to its "resting" spot, gets held up and that error code reappears. Any suggestions for repairing this would be appreciated. Was a good printer up until this point. Worthless at the moment. HP support was of no help, all they wanted to do was take all my contact info, (to resell I'm sure), and try to sell me a "discounted" printer. Thank you.
Did you ever figure this out. I have the same problem
@@tobifasola2017 Unfortunately, no. I ended up buying a used printer on Facebook Marketplace that so far has been working fine. I donated the 6968 to an organization in Cleveland that teaches young adults how to take apart and repair computers and peripherals. Figured if nothing else, it could be a teaching tool for some students.

Yeah this is spot on. I think this is the problem where most of these "paper jam" issues come from. I just took apart my 6962 and that tray is overflowing with messy ink and it won't move backward as it's supposed to. I don''t think it's a salvageable operation unless you're willing to get really messy and replace a bunch of tiny parts
What size hex for removal of the. 10 screws holding the top portion.of the main portion of the HP - mine is HP6978 and has a very small HEX top/slot on each of the 10 screws.
Hi. It is a torx screw size 10. T-10
Okay so the print head is out , the carrier unit is out.... am I just supposed to clean it all and reassemble? it’s quite caked with black ink...The head was jammed but there is no broken parts, I’m not sure what the problem is that I’m having.... is there any advice you can give(something to watch for in that area?) thank you for this vid!
Thanks for this comprehensive video! I'm trying to fix an issue where the ink carriage is stuck and I believe there is a part that is blocking it. The printer is only three months old and it's hard to believe something as simple as unplugging it while it's operating could brick it. Do you have any advice for this issue?
I have the same issue. I forgot to turn off the printer and we had a power outage from a storm now the carriage is stuck. If you found a simple solution let me know. I tried to remove the first cover but could not get the screen to come off. I cannot figure out why the carriage is stuck.
@@seeker1970 Hey Will, nothing yet. I took it apart almost completely and can't manage to move the ink carriage. There's something underneath it that isn't letting it go back down and because of that it will not move down the track. I got the squaretrade warranty at Target when I purchased it and am going through the process to get it replaced now. Sorry I couldn't be more help!
@@seeker1970 Good news actually! I managed to fix it! An HP rep had me unplug everything and then hold down the power button for ten seconds. He said this drains the printer of any power completely. When I plugged it back in it printed a test page perfectly fine. Give this a try and I hope it helps!
@@ShinyShandera Thanks for the tip but it did not work for me. I might try one more time to take it apart...with a hammer. I think this is the last HP printer I purchase. I'm going to try another brand. One with less expensive ink cartridges.
Excellent How-to video! Thank you. Please do one for how to fix HP 6968 carriage hangs up on the right triggering false paper jam error. Goes thru initialization cycle with no problem until it reaches the very end where attempts to move carriage to the left for printing but can't because it gets hung up on the ink catch basin underneath that does not fully retract out of the way. And thanks again!
Hi. I will try to get the video out if successful. Thank you very much for the suggestion and for your support!
@@303electronics Is this video out yet? The carriage is stuck in the right side in my HP 6978 printer. I need to get it to move freely.
@@303electronics I am having the same problem; printer carriage will not slide to the left as it is caught on the catch basin under it. At 10:57 the video mentions that something is slid back to release the carriage, but I cannot see what was done and have not been able to free up the carriage even though I have it disassembled to that point. A bit more explanation would be GREAT!
Thank you thank you thank you, I'm going to remove the printhead for cleaning even though I could do that while it's installed but I don't think I could do it properly without removing it.
You are welcome! Glad to help! Good luck on your project!
Thank you so much for this! I had to clean my printhead as my printer was not printing black. However, after putting it all back together, now my cartridge is stuck on the right. I manually turn the wheels to move the bottom part of the printhead up and can then move the printhead around. The printer then just cycles it back and the cartridge gets stuck again... Any recommendation on how I can fix this issue? I have the 6968
Same happened to me, did u fix it
What is the attachment needed to remove the scruise I don't seem to have one
Hi, Very useful video, thanks. I have managed to remove the top cover to get at the print head which I aim to replace. I have ordered a new print head from ebay (Chinese supplier) for £29.50. Says it is compatible so crossing my fingers I can breath new life into my HP Officejet Pro 6960.

Ok i did it. But how do i put them back together now?😩😭
Play the video in reverse, simple!
Thanks. Thats a pretty good idea
Thanks for sharing this video @303 Electronics, I feel more confident in taking apart this very printer I have due to no black ink printing out from my new cartridges. I even bought the recommended cleaner you showed in another video. I do have one question though. When I open the printer top head to reveal the printer head with cartridges and once it moves to the middle position so that I can remove the cartridges, I notice that to the far right (where the printer head stays in default home spot) that there is a puddle of black ink on the ribbon connection and on the bottom of that area. Almost as if ink spilled in there. Is that normal? Thanks in advance.
Hi. It's best to remove that grease. Use a q -tip and use caution to avoid damaging any fragile parts.
Oh ok. So it's grease? Yeah I noticed it had some type of white pad underneath it. So I wanted to make sure before I did anything just in case there was a reason for it being that way. But I can definitely tell that ink splattered around that area too.
Thanks for posting such a thorough video. I have a 6968 and the black nozzles of the printhead were thoroughly clogged. I've unclogged many hp printheads, but this was a first 6900 series and I was able to follow your instructions to remove the printhead which I cleaned and reinstalled, but the problem I'm having is the the carriage is now slamming all the way to the right HARD. Then it tries to push farther right before rifling back left and getting stuck 1/2 way producing a carriage error. I did not remove the encoder strip like you did in the video. I left it in place. The nozzle was clogged before disassembly but the carriage moved fine without issues. Is it possible I damaged the encoder strip or maybe didn't align it with the carriage properly?
I'm having the same issue as stated
After cleaning the timing strip and shaking vigorouly it started to print
a test page before sucking up a bedsheet oh my same thing again
Did anyone fix this carrige jam issue
Thanks for the advice bud, I just broke my printer following your directions.
I’m sorry, but these instructions are wonderful. You broke your printer yourSELF. Perhaps you have never tech’d an hp printer before. I don’t know; I only know that you are an angry, rude person.
Carriage removal is much easier with one screw loosened at 11:11. Then the tensioner will move to allow belt to grow and get over the rim of pulley. You're trying to move the tensioner here, but it won't without being loosened.
TIME POINTS for review to reassemble:
12:12 carriage
10:10 carriage rod
11:55 print head wiring
5:45 print head springs point outwards
7:20 print head
7:55 circuit board
9:03 rear port covers
2:55 touch screen
Thank you for pointing that out. Have a great weekend

Thanks. I was scared. My next question.
What do you clean the rollers with.
Thanks
Looking at the front of machine, in the right hand corner, under roller bar there is a unit that appears to move back and forward .. it is covered with what looks like excess ink. Suggestions on how to clean and/or remove. What is this part called?
Hi. I think you are talking about ink gunk which builds up from excess ink over a long period of use. I suggest removing the hardened gunk with a q tip or any small stick. I use a plastic knife or a screw driver.
My paper is jamming on my 6978 as it is about to spit it out. I see that a little spring is off on the roller beneath the ink printer heads. There are 5 double steel little cog wheels just below the ink track and it the one on the right that has the spring slipped off. How difficult is it to fix and reattach that spring?
Hi, thanks for your great video. I still have a problem to take out the carriage. In your video you don't show clearly the way to take it off to be able to move it to the middle, as it is stuck on the right side. Could you clarify this parr or send me a little video for this part? Thanks in advance! Martin
Hi. There is a mechanism under the ink carriage thtvslide back and forth. Gently push it back with a screwdriver. That will release the carriage and it will slide freely.
@@303electronics thanks it worked!
That was my problem, it looks like the ink dry and leave the head stock to this mechanism. Clean it up and hope I can put it together again
I have the same problem on my 9019 hp printer. I don't see any mechanism under the ink cartridges?
Ohhhhh... I now see the tray release buttons are 'underneath' my 6958; my old HP release buttons were visible in front....😀 and easily released with my fingertips. -** 6958 sure makes it 'harder' to remove that tray to look for paper jam.....

Thanks a lot for this video! Very sorry for having so mention this, but I still need help. So if anyone knows how to solceproblems with forwarding paper please let me know! Printer 6960 accepts paper. But the forwarding always stops wenn the paper is in the back on its way half through turing over the rolls. I can remove it easily and completely and I did not find any little piece of paper left in there. It did print once printerinformation. After that no sheet came through to do a proper printint. It always says paper jam. I need help, please.
I have an office jet pro 6970 that I replaced the black ink after a warning indicating it would need replacing. After replacing only the black ink cartridge the printer stopped printing black. Even after many attempts to clean the print head from the menu, the other colors would print on the test paper but not the black. I also tried to print a copy of page and the paper was blank. I followed the recommendations on the HP site and unplugged the printer from the power outlet for at least 60 seconds and that did not work either. Manually cleaning the printhead with alcohol did not work either and I repeated the process many times. I have come across an article saying there is a hardware circuit that stops the black from printing but it did not give any details or information how to resolve that problem. I was contemplating the idea of buying a replacement printhead and installing it myself but not sure if that would make a difference.

Hello, sep 2023: i followed your video w intent to replace the CMOS battery 2032 on my HP 6978 to see if that would make the printer print.. After changing the battery and putting. The orinter back together, the screen on the panel displayed a blank white screen but no menu. I removed new battery and replaced w old battery by taking the printer apart a 2nd time.
Again, the panel displayed a blank white screen. I played w buttons and checked ribbon cable connections but nothing.
I replaced old battery w another NEW 2032 battery by dismantling a 3rd time. After putting it back together, and making sure that the ribbon cables were correctly put back together, the panel is still displaying a white blank screen.

More to disassembled the rest.. For full.. Cleaning inside of it.. Coz a lot of inks was leaked inside the carriage.. Thx a lot..
I'm trying to put everything back in place but I'm having a hard time knowing how the timing strip was being held. That little piece of metal that holds it, I can't figure out how it goes.

Hi, to follow my previous message. Where exactly the carriage holder is situated on the carriage? Idon't it clearly on your video. Regards.
Thanks for sharing! I got to the point when you release the carriage so it can slide to the left (10:56) but the video doesn't show where exactly you release it...can you please provide some guidance? Thanks!
I just moved back the "carriage lock mechanism" that is located under the carriage. You can move it with a screw driver by pushing it back. You can have it unlocked by opening the cartridge door and unplugging the printer. The carriage releases after you remove the clamps on both sides of the rod and release the driver belt. Please let me know if this was what you needed or if I didn't explain it.
@@303electronics Thanks for replying! The failure I have with the printer is that the carriage is stuck on the right (slightly moves to the left but no more). So it can't slide to the middle as happens when you're replacing the ink cartridges...Not sure where is exactly the carriage lock mechanism.
I sent you a photo of the carriage in my printer through a message on your FB page, if you can mark the lock mechanism on the image and send it back it'll be very helpful. Thanks!
First, thanks for some great videos, explaining things clearly in plain english & a lot of patience!!
I'm having a somewhat similar problem with a 6978. I keep getting 'paper jam'' error even after clearing the paper path & checking it multiple times & the printhead is frozen to the right & will not budge. I've tried powering off & on multiple times.
It actually started with a tree limb falling across a power wire somewhere. Power was lost quickly & apparently cleanly & was restored in a similar manor. The printer was idle & plugged into a power protection outlet. I have contacted the electric company with no help. I have not contacted the outlet company yet.
I am comfortable with a V-O-M meter good with a soldering iron, so any voltage checks would also be appreciated.
My only problem is that I'm 72 yrs old & not as good as I once was & have a very limited supply of cash or I would just replace it!!

@@303electronics It seems like multiple people in the comments (including me) went through these steps and the one main part we need is done off screen. It would be great if you could post a 10 second followup video showing how to move this "carriage lock mechanism"
Hey thanks for the video, please help I have followed your instructions and carefully cleaned my printhead of officejet pro 6960 but now as I am powering it on the print head carriage is not moving freely it is going on full force and in display jam error is occurring please help for this
Hi. The problem is that the clear strip in the bavk of the printhead needs to be in that sensor area. Make sure it is dry there too. The timing strip is on about 3 millimeters in width and is attached from one side of the printer to the other. It controls the carriage when printing. Since you removed printhead, you misplaced the strip. It just needs to be repositioned inside of the sensor. Let me know if you were able to figure that out. Thanks.
@@303electronics Sensor area means those 2 black bulge type thing at the back of print head??
@@AkashDeep-lw9bw yes

I replaced the printhead exactly as shown via this excellent video. Still only prints blank pages. Put in new ink, updated firmware, calibrated and all that. I think these printers are garbage and designed to fail. They are a serious waste of plastic and resources. I’ll never buy one again.
My scanner that scans the flatbed was stuck and wasn’t going across the glass below. However the scanning documents from the Documents Automatic Feeder still scans ok. How do you take apart the scanner bed to unstick the light bar? You didn’t show that on the video.
Hi. When you remove that assembly that has the scanner bar, flip it over and there will be about 8 screws around the perimeter. Remove those with a t10 screw tip and unclip the top portion from the bottom. Be careful to not let the inside parts fly out.
fixing printers reminds me of manually flipping rotisserie chickens.
is there any place that i can purchase the small white plastic gear that is on the right side of the rod that goes through the black and white thing that has rollers? it broke on mine and glue is not keeping it together.

I removed my printhead to clean it by soaking it in water. After I reassembled the printer it says, "There is a problem with the printhead" and won't do anything. What do you suggest? I was careful to get the timing strip back into the printhead in the right place between the sensors.
It's very likely that your printhead has failed before you started cleaning it. They do that sometimes.
@@303electronics I got it working again after reinstalling it, powering off the printer, casting a spell, etc. My blue and yellow still won't print, though.
Do u fix t
Printers
I do, but I do not have a service center for public, nor I accept ship ins for service currently. I fix them for selling.
@@303electronics oh ok thank you so much I'm following your video my printer missed up
The black ink wasn't coming out and I'm having a horrible time 😫 trying to do this I been here since the morning
Hi, why not print my 6978 printers, only color ink printed?
Hi. The black ink cartridge needs to be replaced or black nozzle needs cleaning.
@@303electronics I did those two and still doesn't ink, the only color
HP told me I have to buy a new printer because my print head went bad.. is there a way to buy replacement parts or clean the print head to get it to work again?

On my 6958 the home light doesn't come on now to access things like head cleaning and other things as alignment etc. before it quit there was a quick flash message that I think said 631 circuit failure. Not sure of that number as it went on and off so fast. Any ideas to fix or scrap

I have this exact printer, and I'm here because it seems my yellow has gotten clogged, so I'm looking for a solution. When my HP Officejet Pro 6978 works as it should, it outputs great quality prints and does so pretty quickly. However, when I haven't printed something in over a week, it seems it always has to wake up and go through this lengthy maintenance process before it actually starts printing what I need, which is pretty tedious to say the least. With that said, I would HIGHLY recommend against purchasing this printer or any HP printer based on this platform design. First off, the ink cartridges are among the most expensive on the market. For a set of genuine HP 902XL cartridges, (XL meaning the larger ones that hold more ink) you're looking at right around $100, and even on Amazon or Walmart a full set runs around $100. Then there's the fact that this printer absolutely BURNS through ink like a fighter jet through fuel. I don't think I've ever gotten more than 50 or so pages from a single XL black cartridge. We do only occasional printing in my home, never for any sort of business purposes, and mostly for stuff like an occasional picture our son has drawn, and maybe a couple dozen pages of text documents a month for doctors visits or food recipes. At best a set of these cartridges lasts us maybe 3 or 4 months. We easily go through $300 in cartridges a year in the four years we've owned this printer. I've lost track of how many times I've uttered the phrase "WTF, I swear I just replaced these cartridges!!!"
Agree! I fixed my printing problem but then I remembered how expensive the ink cartridges are! For what I've spent on ink, I could've bought a few brand new printers! I'm looking into a tank printer where you literally fill it with cheap liquid ink when you need to and it lasts a long long time.
I just bought Hp officejet pro 8160.. it has been sitting in storage and is dusty. It says it doesn't recognize printhead. . What should I do?
Try to remove printhead and clean the contact area. Since it has been sitting in storage for awhile some ink may have spilled on the side and is interfering with the contacts between prinhead and carrier.
@@303electronics Clean with what? I did try to clean earlier.. though inks are low... I will try again
@@callisto6213 i usually clean with alcohol swabs
Question, a piece of.my office jet has come off when I was trying to fix a paper jam. I wonder if you'd recognize it? I can email you a picture.

Thank you very much😊
Brilliant quick and efficient and informative teardown. Thanks
I have this printer and it stopped printing black ink. Like, zero output. Ran clean print head about 30 times this week, nada. New cartridge, genuine HP from Staples, nada. Tried pushing alcohol through the head and used compressed air to clear as much as possible, nada.
This lead me to your video.
Took print head out and brushed with denatured alcohol and a toothbrush, then wiped with microfiber, nada. Any ideas at all? I'm going crazy.
Did you ever get this fixed? Having the exact same problem
@@bethanyniermeyer2177 No. I took my baseball bat to it.
@@TonyHarlan that sounds super therapeutic to be honest 🤣
Same problem here and HP won’t do anything to acknowledge there defect in the product. So many of us with Same issue
Wish I could have found this last night
What type of screws were there because I don’t know what type of screw driver to use
Hi. Star shaped tip, t-10 size
Ok thanks man!!!
Thanks!
I did it no parts leftover 🎉😊
Removed the printhead on hp 6962 to clean it. Then replace the printhead. Now get a code on screen saying problem with printhead. Any way to fix this problem?
I did the same thing, I am curious if it has to do with the encoder timing belt? If there is a wrong way to put that back or not.. I tried flipping it upside down also... still nothing... Printer gives me one or more cartridges are missing or damaged error, yet never did before until after I took apart to run water through the print heads
Same problem. Did you guys solve it?
Spring has been sprung @5:50 hehe
Hahaaaa. Yes, indeed!!! 🤣🤣🤣🤣🤣
Me funcionó el método pero mi cartucho cyan es el que creo está dañado por qué sigue imprimiendo a rayas
Y ahora como la armo ?😅

My printer is leaking ink everywhere what do I do
Its possible that the tube that goes from the suction to absorber pads is not connected properly.
Am I the only person who has no idea how to “move the carriage holder to the back”? 11:00 the camera angle doe not show what is happening.
Same
my paper is jamming after it prints. no coming to exterior tray
