#ElectronicsCreators #DumpsterDiving
If you go to the counter screen and hit the stop button then 00 stop 01 stop it should take you to service mode so you can dig in deeper and recalibrate it. I used to be a copier tech and worked on a few thousand of them over the years
For more information, this model range is one of the best ever made and can do a million copies+ with only basic preventative maintenance. 300k is about when things start to wear out, so check the life on them. These would be solid reliable machines even today but like everything with a computer in it, the security was quickly outdated and doesn't support some of the more modern protocols for connectivity. It's really only a generation behind being replaced by the 8 series models. You can tell by the last number in the model number. There's also a black and white range which is basically the color machine with the cmy parts removed. If the machine has been wiped including the life counters, you can tell wear on most of the serviceable parts by looking for a band of color missing on the imagine units on the drums. The coatings get grinded off with paper dust and toner over time causing electrical arcing. Most copier jams are actually caused by sensor or timing issues causing a stop rather than run to catastrophic failure.
@@jeffreyorion Thanks for sharing all of this 🙏
While you at the service mode, try "halftone test", with different colors, you can see if there is any problem with any of the CMYK drum/developer unit. Some of those problems can be fixed by simply cleaning the drum corona or the laser mirror below the drums (both can be with a white stick thats behind the door that you just opened to turn on the machine) There is a test for paper passage too, for all the trays. Each tray has 3 pickup rollers, usually they wear out the fastest and causing paper jams. After that, it can be the clutches on these units. But be aware that these machines are not cheap to maintain, some problems can be fixed temporarily, but most of the times you need new parts. Like, if the drum coat wears out, you can increase BIAS voltage of the dv, but that's not gonna fix the problem for so long.
I am a copier tech also. This man is correct. Parts are available online, as are manuals . These machines are designed to be serviced and kept running. hang on to it and you'll never buy another printer in your life.
I can also confirm that what the OP here said is correct.
I too work on these things, alongside horrible CANON printers (very anti-consumer) and the fairly repairable Brother printers (very pro consumer, has been known to give customer's service manuals for DIY repairs out of warranty) and the HP printers I no longer touch since they're written off at roughly 300K prints (250K is the limit for part replacement, 300K we're not allowed to even bother putting it in service, their old stock used to do in excess of well over 500K prints with a little bit of TLC. Much of the business oriented laser printers are just rebrand canons, thus worst of both worlds).
HP took over the Samsung printing division, thus expect worse Samsung printers going forward.
HP has taken design ideas off of Brother printers for one of their printers we're servicing lately, they're best described as looking like an "eastern bloc Communist's housing", it defo has that "you will be happy, or else gulags" vibe to it, which is fitting given HP's "Insta-ink" and ink based DRM shenanigans lately.
HPs based on Canon's equivalent inkjets often don't have the same carriage mechanisms, intentionally so as to keep customers from figuring out they could get cheaper ink from one to bodge (hack) into the other printer, especially as the carriages use different chemistries of ink.
Edit:
Also, this Konica printer is based on the Ricoh equivalent.
A few things give away the fact:
Painted fuses in the PSU, the inductor styles, folded ground tabs, etc combined shows that PSU is made by the same designer as the one in the Ricoh SP4520dn.
The choice of cable colours with connectors to make breaking the harness apart easier to do without having to completely unroute the harness (They're more obvious in the PSU section)
The choice of screws are akin to what Samsung use though, so not sure what's happening there.
Bet Someone got fired and said I'll show you, then turned off the main switch so no one knew how to turn it on.
I used to fix these things for a living. Do you have any idea how many service calls I had to attend to for this very reason? “Copier not working”. 🤦
@@mikestewart4752 Or not setting paper guides right in the cassette, or lines because they don't know how to clean the scan glass(es), or breaking stuff while trying to put the toner where the paper goes. 95% of my calls are user idiocy.
@@caseycornett5182 THE SCAN GLASS!!! How could I have forgotten??? lol.
@@caseycornett5182 We reported the problem back to dispatch as ID-10-T. 😁
@@mikestewart4752As a scanner tech, I feel your pain. "There are lines on the image"
"Have you cleaned the glass?"
"Yes"
Goes to site, cleans glass.
I wouldn't be surprised if the contract finished on the unit and they didn't want to continue to pay the yearly maintenance fee to keep it running, so they decided to cut their losses with it and likely get a more modern one.
One of the places I work at here in Western Australia, we lease, once the contract runs out, we either buy outright and move it to a different location and replace with a new lease, or send back to the leasing company and get a new lease.
It's often not worth continuing to pay the yearly maintenance fee on these things once a lease has finished.
A right call. I owned over 10 printers over the years. They were all complete rubbish, every single one. I now print at work.
FYI, it's rated for 100,000 pages / month!, so 300,000 total pages is nothing.
yeah 800k is about what we would suggest before its becoming worn out
And those toner containers are ungodly big. Sagan has to develope a lot of games before those run out.
@@JCGver standard size for A3 copiers
@@rrrohan2288 yeah standard ungodly big for home use 😃
Right. I am a copier tech and I see machines that have millions of clicks. These are super expensive machines(think 25k+ for many of the larger color models) and they are meant to be used to death. On the new(ish) models like the one you have the engineers went into a lot of details about serviceability as you noticed. 1000 plus page service manuals are kinda the norm although once you get used to working on a model line from a manufacturer you don't need them very often. I think I might look up something in the manual once a week if that and I work on probably 100 different models across 2 different manufacturers. Most common faults are going to be consumable things like drums, fuser, rollers, and ADF pickup/sep rollers. All of these things are designed to be easy to replace and you should only need a PH2 screw driver. Good find even used this thing would probably be a couple grand working.
You don't have the finisher else it would be able to staple and perforate ;) the network plug is on the back right behind a cover. We have the C558 with the bottom bin as dual (or quad) A4 bin. If the A4 is gone a full carton of paper goes in the printer :) There are normal handles on the side to pick it up with 2 persons.
Most likely a leased unit, and after 10 years they get a new one, and trash the old one.
Nice score! I was "yelling" at the video. I've worked on so many of these and knew exactly where the main power switch was.
With the old printer doing that interesting pattern, it is now able to print money... via art.
Dave Bucks
@@EEVblogVoting for fluke artwork for the fiver 😂
@@EEVblog - Guess this was Dave's last video on TH-cam.... he's going to "make" lots of money. lol jk
We has this exact model in university in like 2014, certainly had networking, but ours also had a third party card reader
Dumpster room.... nah more like a treasure room for Dave :-D
I found a $700 HP laser printer in a dumpster outside a model home being remodeled. Only had 600 pages on it. Can’t believe the stuff people throw out.
I always wonder why they don't sell it? Like it's really not that much work to post it on internet and let someone pick it up for a price... Like... Really, people are lazy bunch, aren't they?
Well, most of the time there's something wrong with it, which isn't easily fixable without spending more than half of what a new one costs. And meanwhile needs may have shifted.
It's an HP. Unless it's 20+ years old, it belongs in the dumpster.
@@lazymassmaybe they don’t have the time or interest on selling them. Selling ”cheap” things can be time consuming and waiting people only to be ghosted.
More money than brains
These are the contract machines we have at work; we have two of them. One setup as B&W and the other setup as color. They are fantastic machines, they just run and work and thats it. Their color prints are of amazing quality as well and really fast. Envious of the score!!!!
BTW the thing does have a stapler, AND a puncher. Also the bottom "utility drawer" is a spot for a high capacity paper-lift drawer that will hold a stack of 4 reams of paper. 🙂 Ethernet is on the back bottom left IIRC.
Wow what a find!!!
I'm still using a Canon black and while laser copier/printer I bought back in 1999. It prints laser sharp pages in 5 seconds dancing out those clog prone inkjets. I change the toner once a year, and everything still works perfectly. :)
The real champion of these things is the ADF scanner on the top. If you need to scan a heap of pages and the rollers are clean, it will absolutely tear through double-sided pages and PDF them on device.
That is, if it is a single pass, double sided scan to scan both sides in one pass. I'm betting though that since this is a low end machine that it has the standard R-ADF (Reversing ADF) that uses a solenoid with a gate to flip and scan the second side. Single pass would be a significant upgrade and definitely cost more money!!!
Somebody had a 300k pages service contract I guess. It‘s a shame that so much working stuff goes in the dumpster.
Its 10 years old now they probably leased a new one so they could write of on tax.
Its most likely they went out of business. These service contracts can be 10-15 years and cover well over 1 million copies. I work on similar copiers that have 3 million plus pretty regularly.
@@caseycornett5182 FWIW here in Australia our KonicaMinolta and FujiXerox (now Fujifilm) printer contracts have always been 5 years. The machines always gets replaced at the end with the option to keep for a small charge, or return.
I'm so envious that you have a dumpster room that is literally a cornucopia of good stuff.
We had a whole bunch of these machines, in different sizes, in my old company. They are quite reliable, if you maintain them regularly. We used them as printers and network scanners (scan to email/folder [no cloud rubb..]). The ethernet port is on one of the back corners behind a panel, but I don't remember if it's on the right or left side.
Great score! It's a bobby dazzler
Thats a nice find. I dont have much experience with the Konica uniys, but tons of Ricoh and Fuji experience. These are typically purchased with a service contract that provides service, toner, etc.
I've worked on the Ricoh/Savin/Lanier/Gestetner brands of machines...Konica-Minolta beats 'em hands down on quality and servicability!!!
BTW, your old printer could probably be fixed economically. The crazy color patterns are repeating in the process direction every 2 or 3 inches. This means the problem is most likely a bad Bias Transfer Roller, which is a fairly cheap and easily replaceable part. I didn't get a good enough look at the machine to nail down its exact model, but most color machines that size use a one piece module that contains the transfer belt and all 4 primary Bias Transfer Rollers. Replacing that could very well have that old machine running fine again.
I've been a printer and copier technician for years, seen a lot of that kind of failure.
Called "defect repeatability pattern” if you roll it into a tube and match pattern to pattern, you'll know the *EXACT* size/diameter of the roller that is creating the problem!!! I believe the KMBS service manual in the back gives point-to-point distance of each kind of roller!!!
I liked that artwork description. You're quite the wordsmith.
Some day Dave is gonna find a literal bar of gold in the dumpster lol ❤️
I'm a technician for mainly Konica Minolta machines, this is a good model. The parts in these last a very long time. They have a few common issues but it should last you a long while!
You held that modern art piece upside down.
They like to hide the main power switch behind the toner panel door or sometimes on the side where it's "more" visible. They're all designed differently of course! I learned that from years of part-time experience in retail printing.
Nice find and glad it's working! Also, thanks for showing us a little tear down too!
Mr Lucky. Funny if it was leased and the leasee did a runner from their office and just dumped this on the way out. The doctrine of Finders Keepers come in to effect. 😁
Great find. I got a free Roland JV-80 that had the runny red glue and some keys that didn't work. Lye and acetone and it sorks fine. I love fixing old stuff.
I used printers like this at work for many years and never had any problems with them. Great printing quality, fast, automatic scans, automatic 2-side printing. In my company you could press "print" and print your stuff on any printer in the company, that is super convenient. This is the perfect printer for business
A new employee was told to take the copier to the storage room, he rolled it into the dumpster room and now no one knows where it is......
In my experience these Konica Minolta copiers are well-built and reliable, certainly a lot better than the junk that Xerox is making at the moment.
It also looks like your old unit might just need a new cyan drum cartridge.
Great find, Dave! 👍
Free office photocopiers off of gumtree are my #1 source of mechatronic parts
I've sold two before I've found in the dumpster. Didn't go for much, so yeah people are happy to have them picked up for free.
@@EEVblog this one new is worth 2500 usd dave so it still worth quite a bit
I have that exact model on my office. It's somewhat old but works perfectly fine!
It definitely can be networked, and it definitely does stapling!
I didn't see a finisher on it. I don't work on Konica but they aren't much different from other brands and other brands need either an internal or external finisher for stapling, hole punching, and stacking.
@@caseycornett5182 I dont know how it works because we never use the stapling feature, in fact it always warns us that it's out of staples.
But the fact that it warns us is enough to know that it can do staples.
nice score!
Great find! We had the same unit in our office, other than jams it was pretty solid !
3:40 for a very brief moment I was wondering why you would blur parts of a bloody PSU 😂
What a lucky find. Nice to have a dumpster room like this. It's been a very long time since I've found a lucky dumpster dive like this.
I manage similar printers at work. If you have a windows server running, you can manage the device and use all the fancy print features from any computer on the network.
Awesome haul ❤
I have almost identical one at work for years.
Had no idea there's a touch pen, need to check it on Monday...
What an awesome score! Your sooo blessed lol! 😎🤙🏼
What a find! Hope you can get it networked
Yes, it will do stapling and collating if you have the module for it.
Love your work
That's some quality, high-falutin twattle you wrote about your modern art piece! I'm pretty certain you wrote it in jest, as I too am always amazed by how much social commentary artists can read into their blotches.
He probably used ChatGPT or something, because the one thing LLMs are actually good at is producing reams of complete bullshit.
.... or today: It was most likely Chat-GPT. 😀
I was a kid in the 80's and it blows my mind how much printers have been improved but probably not as much as Johannes Gutenberg would be.
i had a fun opportunity to participate in a C-level meeting at KM for exactly these kind of MFPs. i was a lead software engineer for a totally different division, but there was a chance for cross-over / integration across products. seemed like a fun project but sadly it never came to fruition.
Holy crap! What a score!
I can't tell you how many Cherry Switch Keyboards I pulled off of machines like this that had been taken to the boneyard!!! 😂
Nice find!
omg dave! you realize the banner printing mode lets you feed in a sheet 30cm x 1.20 metres long ? that is a really really cool feature
and if you can line up 3 banners, that is 90cm x 1.2m of a color poster print for the wall... -or- it can be like some really large stencil to stick on and cut out onto another surface, such as some large board or panelling. to do some elaborate diy ornate patterning cut outs or something quite artistic and decorative works. for home interior design etc. 👍
wow, that’s a sweet find there Dave you’re a lucky man haha
Make sure the unit wasn't leased and just pending collection from end of lease 🤣
I am out-just a 17yrs old Thinkcentre was all I got from the dumpster. Bios repaired-working!
Jammy Git ;)
A quick clean and replace those cartridges from 2015, and I can see no reason why this won't last another 10+ years.
Nice one Dave.
What a great find Dave. Greetings from the uk 🇬🇧
Button is behind toner cover
I work in a college in the UK. We normally replace our MFDs every 5 years but stretched to 6 last time because of lockdown (year of no usage). We had 35 of these Bizhub C284e but with an extra Tray 3 that took 4 reams. Very little issues except consumables in 5 years accross any of them. When our 284es got retired most had 200k-400k prints but we had a couple at 800k-900k prints that were still going (starting to rattle and sqeek a bit though).
The spiraling on the toners is different on each model so you need the right toner or you can''t insert it. Id guess they threw this out because it can't share consumables with its replacement.
Konica Minolta also it's one of the best brands of copiers, high quality prints and very very reliable, the HDD I don't think it's encrypted but on some copiers (like Toshiba) are encrypted with Wipe Technology, that wipes the drive when it's plugged in on a different device than the copier it's bonded to.
Amazing to find this in the dumpster - just imagine what this cost when it was bought! 🙂
Bloody power switch on those things. Took me ages to find it on the ones at work. I've now learnt!
I still like talking stuff apart. I'd love to find a broken one. 🛠️🤓
My employer (auto component manufacturer) used to lease a bunch of these (until the leasing company upgraded us a couple months ago). They had the usual printer issues but otherwise were solid units... we'd print a lot of 11x17 (yankee A3) on it for signs, mechanical drawings, and electrical schematics. Certainly ran a lot better than the "backup" HP color laser that always rendered color prints as splotchy abstract art... (the leasing company could never keep that one running right).
Our units didn't have the perforation option, but they did have staplers... very handy when printing a stack of schematics to put in a PLC cabinet...
Splotchy...Probably weren't using OEM toner but a 3rd. Party toner that needed slightly higher fused temperatures to bond the toner to the paper, but since the temperature wasn't high enough the toner was partially sticking to the fuser hot roller which was leaving "toner offset" on subsequent pages from the previous pages.
I think the reason copiers at this level are designed to be easy to service / repair is they were leased with a SLA.
The Magic Dumpster delivers again. Memo to Dave - RTFM
Now that's a very good score there Dave because causes photo copying machines and not cheap especially that one it says buying a new one
Wow that's a nice find, I wonder why they got rid of it. Maybe it's haunted? lol.
Former owners probably just went to a leased unit with a service plan. You don't have to provide anything but paper, toner, and power.
I was literally laughing my ass off! We have one of these in the office and scratching our heads… then found the hard power switch.. my uni education not fully wasted then
The hard drive is for processing image files, and storing user boxes on screen ,retired Konica engineer.
in wayne? i had the opportunity to visit a few years back and wow that facility was gorgeous
As a Former Master KM IT tech, ya the front door is a tricky find! I'm glad you found one as from my perspective everything from the electronics / encryption connectivity, etc is so very well devolved. This model is about 10 years old but so very relevant still. ( that boot screen is just the "default" 3rd party vendor start up screen , it can be reset from the service menu. ( Sorry i can't help here *wink* )... ethernet + usb printing included, no wifi
+3 to 5 is expected from these printers ... they are also only sold with service contracts for free drums/toner ... (no staples) can get it as a finisher that attaches.
I used to work on Konica-Minolta!!! Darn Good machines and pretty easy to work on!!! Did you find the Main Switch behind the front panel door???🤔
That is a score to keep. Even if you sold it as second hand, you would get 1000 USD for it. 350k pages for this device is nothing. The monthly recommended use is at 12000 pages. I believe spare parts are still available. An Dave yes, a stapler and sorting module are an option. Pricy though.
The colour reproduction is quite good. Seeing an IP address in the device info screen indicates it has networking capabilities of some sort. Amazing they tossed out the CDs, manuals, and other accessories with the unit. Often the device would be tossed out separately from the other parts.
Brilliant!! I would like to share my own dumpster find, a 50 inch LG plasma screen tv manufactured May 2014. Worked fine when I first powered it up. HDMI input works. I found a remote for it on Amazon, it works with the tv. The screen has a quite a few dead pixels on startup that go away after a few minutes of warm-up. It looks like someone tried to take it apart because about 25 percent of the screws on the back panel are missing. Otherwise pretty cool find.
On one of the early screens shown that showed the toner status, the black toner indicator had a highlighted box around it. That made me think the black toner is near its end.
PHYSICAL POWER BUTTON IN FRONT COVER
Stay watching 🤡
In the older days some of them were not orange. And then it was a quest.
@@eugenijusjanuskevicius2292 on our older printer the button was a big cluncky switch on the right side near the display. But hey that's history :+
@@Damicske it was Sharp, if I recall correctly. The power switch was in the same place as in this Minolta, but it was grey, in a grey body and shadows of the developer unit and toner bottle. No, it wasn't clearly marked.
Wow. I would love to own one of those! OTOH, as someone who worked in the industry for many years, you might want to check on the price of legit toner refills, which might give you an insight on why it was tossed out. ;)
This level machine usually has sweet web control once it's on your LAN. Seems as if it pays to rent in this business park, Dave - good on ya.
Great find Dave. I could make a living from this dumpster.
I used to use one of these regularly at my old job, it has Ethernet, these printers have a habit of jamming in the duplexer, especially if you print lots of labels.
you shoudl do a video, explaining how to find good places to dumpster dive.
I love dumpster diving, but i never find anything that has computers, or anything else high value in it. I think alot of people, could save alot of still useful items from being trashed, if we had better places to look,
I often have to restart those printers. Discovering the power switch was a breakthrough back then.
not too shabby
In your defence, that's not the obvious bloody place for a power switch.
The new dell all-in-ones I use as meeting room PCs in work have acquired a honking great red label saying "POWER SWITCH ---->" as they're invariably somewhere bizarrely subtle and otherwise unlabelled. It's ugly, but it saves the IT dept a journey down to press one button, turn around and leave again.
Cheers maat
I am using exactly the same model at work 😮
I’ve got one that I hardly use anymore. These service costs make it a rip off.
Ceramic fuses - nice attention to details.
Renting space(s) in that building has got to have paid for itself by now with all the incredible finds, haha. Not only by selling stuff, but in terms of content creation as well. Just kidding of-course. But that dumpster room is a gift and blessing for people like you!
He owns the Office.
You fell for the oldest trick in the book - 'Big Printer' companies leaving perfectly good printers by dumpsters to get people hooked on buying the toner!!! 🤣
Noice!!! I can’t believe they throw that out.
you cant even give copiers away these days
11:00 WOAH 11K colour prints, that's NOTHING!
See if you can find some heavier paper for Sagan's board game. Look up what thickness card stock if any it can take. Look for borderless printing if it can do that. If you really want to, guild the Lilly, get a cheap laminator.
Winner winner, chicken dinner! Great find. I'm sure you'll figure out a way to get it to print what you want - I'd be surprised if it didn't have any network printer functionality. Gotta love the color prints it makes.
imagine how much e-waste and perfectly good electronics get thrown out every day around the world!
300k impressions is nothing for this sort of machine. Copier repair was not my game but I did work along side a department that did it and it wasn't beyond realm of possibilities to hear of machines with 1.5M on the clock.
be even more awesome if that USB port lets you save images and print them out on it, :) I have my little brother full color laser printer here now, and no other printers really as I left my B&W one back at the last place I was living till I can go get it all, :)
Price is about 2500 bucks. Toner for all colours, 400 bucks.
Don't feel stupid not knowing how to turn it on. We had places where they had these machines for 5-6 years, and they did not know about it (they always "turned off" the machine by pressing the standby/sleep key near the screen).
