Just followed your instructions and had the print cartridge problem. Ribbon was in the right place, but for those that continue to have this problem as I did. Make sure to go back to the beginning of the video where he locks the printhead and then turns the gear back to loosen it a bit and if you were having the print cartridge problem this should resolve it. Now time to buy more ink and my problem should be fully resolved. Thanks for the vid.
Thank you..... You explained the counter ribbon not being in alignment. After many other vids of removing the print head/cleaning you were the only one to mention this very problem.. you earned my sub.
Very nice and clear. I can add that it is possible to test printer without screws and cover only with control panel attached and placed anywere. Also after replacing of the head or cleaning it it is imortant to check were you have placed band with head position data. It can be misplaced and than printer will report that head is jammed and do not move while it is not jammed becouse control do not receive data of position. I advice to clear this band - it can be dirty after all these manipulatins.
Hello, thankyou for the video on replacing the Officejet 4620 print head. It was very detailed! Unfortunately my printer is still not printing black ink. It still says I have ink, I have tried 2 cartridges and now put a brand new print head in, yet still the same issue, it just will not print :(. What else could be stopping this? is there something under the print head? such as the carry that would stop it printing . Sorry to send a message on ebay but i could not figure out how to do it on youtube.
Hi need help fast. I followed your instructions exactly for replacing the print head. Everything seemed fine until I get an error message for all 4 cartridges. All four cartridges are brand new so that cannot be the case. I need help??fast thank you
Many thanks for this video. On my HP 4620 black works fine, but I need to let the printer clean the printhead EVERY time before printing a photo, otherwise some colors are missing in the printed image. Also the yellow ink seems to get dirty inside the cartridge. I use clear cartridges and it seems that (black?) ink is getting into it through the printhead. I have another printer (HP b110) that has exactly the same problem. What could I do?
NVM lol I need the star type screwdrivers and remove the cage, only because I spent 300 on real HP ink, and I have unopened generic I have to go offline if I wanna use because when the HP is only it sees the generic ink and won't work,(or pull it out and use it to refill the HP ones)but ill fix it anyways,6.99 for a set of drivers that have T5 and T6..thats what you used right
I got message on the screen saying (The printhead appears to be missing, not detected, or incorrectly installed) Also i sometimes get a message saying the cartridges are faulty but i perform a restart and it goes away Any ideas what might be the cause of the problems?
Hi Paolo, thanks for the video. Our 4622 didn’t print black anymore (and eventually no more color as well). Disassembled the whole printer, manually cleaned the printhead, the purge pump and every other part which had ink on it. Still doesn’t print anything… any idea what else could be the problem?
Hi! If the purge pump can suck ink and nothing is blocking the conduicts it probably is a printhead issue, you can try cleaning it or eventually replace it. First reassemble everything then try to place some glass cleaner on top of the two sections of the cleaning pad, then rotate manually the purge pump gear and watch if it can suck ink on both sides.
@@PaoloMarcelli it sucks ink on both pads, as I cleaned the purge unit tubes intill nothing was blocking it anymore. Think we will buy a new printer 😁. Already spent quite soms time on this one. Thank you for the video, it was very clear how to do it. Unfortunately, it didn’t solve the problem.
Mai usare alcool per pulire le testine di stampa :/ è inefficace sull'inchiostro. Usa del Quasar Vetri o un altro detergente per vetri come Vetril. Se il problema è solo sul nero controlla anche il funzionamento dell'unità di pulizia, segui il mio video sulla HP Photosmart 5520 in tal caso.
Hi! I used Quasar glass cleaner. You can use a similar glass cleaner you find in your country, but be sure it has density similar to water and doesn't produce foam
I have bought a printer for cheap because it had the same printhead as my printer. But it was not used i think more than a year and the ink has totally clogged the nozzles. When i tried to clean it only the magenta passes a little bit of solution through. 99% of the printhead is clogged with dried ink. I have tried to submerge the bottom of printhead into hot water, then carefully inject distilled water with alcohol into it at all color locations but unfotunately the nozzles are completely blocked, i cant even inject the solution because of the air inside which is trapped isnide. I am afraid of pushing the syringe harder because i can tear the foil. Do you have any solution for this special case how to clean completely dried up ink from the nozzles? Thank you
Thank you very much for your video. I cleaned the printhead of my hP 4622 as explained in the video, but when I started a print a message of a Carriage Jam appeared: Carriage Jam. The print cartridge cannot move. Open the ink cartridge access door , clear any paper or obstruction, and select OK. There was no obstruction or paper jam inside the printer. Don't know how to manage and manipulate my printer would you help me by a clear answer please Thank you
Hi! Check that the encoder strip (a thin transparent plastic strip with vertical black lines on it) is positioned correctly and passes through a sensor behind the printhead. Check also the flat cable connections.
@@PaoloMarcelli Thank you for advise , but the problem was not the plastic strip and the sensor, it was, a tray positioned at the right of the printer beneath the carriage, obstructing the movement of the carriage. the new problem is on ore more cartridges missing or damaged in spite that the black one is a new one Any solution for the problem? Thank you
In my 4620, nothing prints. No streaks, nothing. No error messages. All new drivers, new install. New black cartridge. The HP software has a tab that checks "printhead health". It tells me it's "healthly", but no ink is getting through so I have to assume it's just terminally plugged-up with old sticky ink. I've done about all the cleaning I can...cleaned the printhead while in the printer multiple times with electrical cleaner, alcohol, even acetone. Today I removed it entirely from the printer and soaked it in alcohol. Then placed the tub inside my ultrasonic cleaner! Lots of ink was flushed, but after installing, still nothing. No errors, software still says it's "healthy"...is it time for a new printhead?
Alcohol and acetone? Well... It might be the end of it| Use nothing but glass cleaner with ammonia, nothing different than that. never. Check the purge pump, refer to my video on the HP 5520 not printing black.
Hi, I followed all the steps on the video, and when I reassembled and the printer turned on an tested itself, it said the cartridges are jammed and cant move. Any ideas?
@@PaoloMarcelli Thanks for the comment. I noticed that you said as much in the video, although it wasnt clear where the strip needs to be. Does it need to be under that whole black plastic sensor, or, there is a groove going through the middle of plastic piece, horizontally - does it need to go through there? Also, could it not be something to do with the re-turning the cogs that were turned in order to unlock the cradle at the beginning?
So after unlocking the printer cartridge to manually move it to the center I have been unable to lock it back I have installed everything back the way it was and continue to get a cartridge jam error message on the printer any suggestions?
Hi great video, thank you. I've cleaned the printhead and reinstalled everything. But unfortunately, the printer doesn't work. After power on, the printhead is moving. but an error message comes up showing code 0x6100000a. I noticed also that the cartridges don't move to the middle position anymore, when I ooen the cover. The encoder strip seens to be placed correctly. I can freely move the printhead manually. Do you have an Idea?
@@PaoloMarcelli Thank you Paolo. I've taken the encoder strip from an other printer. This works now. But, unfortunately. black is stil not printing. :-( I will order a new printhead an try it for the last time.
@@yasangelz I resolved my black ink problem by using a can of compressed air and 91% rubbing alcohol and patience. I poured alcohol in the pad funnel and on the back side of the print head until the port became unclogged. Hope this helps if you still have the printer.
Hello Mr... Thank you for sharing your knowledge :-)... I just have a query on the solution used for cleaning the heads. Can we use isopropyl alcohol instead of Quasar glass cleaner? kindly suggest... thank you
I didn't take anything apart, I let the carriage run over 2 semi-dry wet wipes, when it stopped I took an empty e juice bottle with the small tips and push cleaning solution threw all 4, let it sit overnight, soaked up the extra cleaning fluids and ran the carriage back and forth over 2 new wipes, and bam..done
I don't have that printer anymore, and also I did not understand what rollers are you talking about... Maybe you could give me a timestamp of the video where I show them?
@@PaoloMarcelli they are underneath the printer, you just need to open, or move the cove of paper and you can see them and touch, move... here`s the photo. ibb.co/vXX92B3
ciao e grazie per il video, ho visto che hai una testina di ricambio sai dirmi dove posso ordinarla ho la tua stessa stampante. praticamente il ciano continua anche dopo la pulizia ad avere delle leggere imperfezioni.
Hello --- Thanks vor the very good Video and the good ExplanationI could follow + understand. Please see my Prolem what I have with my Printer below -- I need realy the help of an Expert Can you help? or give my a hint where to find help. I'm a German and I have a HP 4622 wich had Problems by Printing. After watching few Videos I Opend the Printer took off the Printerhead and cleand it. After reassembling the whole -- the Printer was printing and the first test print looks quit Ok The first 2 realy prints of a PDF doc (from my PC) showed a dark grey vertikal line on the Paper. So I did another cleaning via the HP printer Menu / display. After that I tryed another testprint. Now there was nothing anymore on the Paper -- !! Printer does not print !! And there is a second issue The pinter-head-unit remains in the parking / rest position!! So I can't change the ink-container (can't take them out ) I would be glad to get a reply or help from you Thanks a lot in advance Rgards R. Louis
Hi! Could you send me an email with a scan/photo of the page with the defect/vertical grey line? That's pretty uncommon! D: As for the carriage being parked and not unloading from the parking position... Does the printer give you a paper jam error at the carriage? Does the switch/sensor that detects the open cover works? When the cover is open, does the printer tell you to close the cover?

Warm water works too instead of solution. You just have to do it a bunch of times

Hats off your work and explanation, god bless you
Hello I am from Argentina. I followed the steps in your video but now the screen does not turn on, what do I do?
Hello. Thanks a lot for this video. You explain very well .
I use to work for HP- The Ink Heads are made for the cartridges. Refilling cartridges not and never is a good idea.
NVM lol I need the star type screwdrivers and remove the cage, only because I spent 300 on real HP ink, and I have unopened generic I have to go offline if I wanna use because when the HP is only it sees the generic ink and won't work,(or pull it out and use it to refill the HP ones)but ill fix it anyways,6.99 for a set of drivers that have T5 and T6..thats what you used right
I think it's either T8 or T10, definitely not T5 or T6 :)
I got message on the screen saying (The printhead appears to be missing, not detected, or incorrectly installed)
Also i sometimes get a message saying the cartridges are faulty but i perform a restart and it goes away
Any ideas what might be the cause of the problems?
