You can see this because one of the nozzle rows - i think for the black ink - is just baked.

I salvaged a color laser printer, I haven't figured out how to fix the one issue it has, it adds magenta streaks when printing in color, bit t at least grayscale is perfect
@@virtualtools_3021 This may mean at best some cleaning is required or at worst a new magenta toner. See e.g. Brother USA answer 59825 for some hints that may apply to yours as well.
@@virtualtools_3021 Is it possible to print with only the black toner? I've found one color laser Xerox printer which is complaining for two colors that are low on toner. Black has enough though.
Have to wonder how many hundreds of dollars of ink is in that waste area, probably several full cartridges of each color. That little vacuum pumps job is to suck your expensive ink out in the name of "cleaning". I gave up on inkjets a bunch of years ago, I only print a few pages a month but was going through several ink cartridges a year. They either dry out or get used up by the periodic cleaning the printers do. What I have saved on ink over several years is now more than what I paid for a color laser and I'm still on the toner that came with the printer. Now when I go to print it just works every time even if I haven't printed in a month.
I’ve seen some printers with ink dumps that where COMPLETELY full of sludge, to the point where it was nearly overflowing and you cannot see the sponge. This is where your ink goes!
The glass scanner bed can come in handy too! I used one as bed for a 3d printer for awhile, and used a glass cutter to make small covers for windows on other projects. Edit: save all the gears too if you're into robotics!
That light pipe off the scanner with it's attached RGB LED... if you get several of them you can make some interesting light feature/displays Also the encoder tape and discs are pretty high resolution, they also usually come with a quadrature sensor which means you can determine direction as well as distance.
Watch the E-recycle videos on YT to see HP printers in their native habitat. Printer technology: where the machine is a consumable like the paper it prints on.
Dave, thanks for doing the teardown on this! I work on these from time to time, but mainly the drafting plotters. The HPs are much more technician friendly than other brands. The unidentified motor and pump head supplies vacuum to prime and clean the printhead. The waste ink goes into the spittoon, where the foam is. Despite their pedestrian use, there's quite a bit of engineering inside. Maybe I missed the part where you found the scanner cameras? They're worth as much alone as the rest of the printer. Carry on!
The sponge is called a spittoon. This is used in cleaning the print head. Yes, they mess all over the place. My old Epson Photo 1800 has a microprocessor that stops the printer after printing X 1000 number of sheets to replace the said spittoon. When my printer locked out, The troubleshooter on the website said there were no spittoons left and they will discontinue the ink cartridges for this model. The reset disk cost a pretty penny to reset the micro to resume printing. Cheaper to buy an new one and pay the exorbitant dollars to buy the new cartridges.
This was an interesting video for me, mainly because I've scrapped 10s of printers for parts. The motors, sensors, springs, and metal rods are my favorite things to collect from them.
Depending on the specific vintage of this printer, there may be an additional motor in the automatic document feeder (ADF) in the (edit: scanner) lid. Some of the newer/cheaper ones actually drive the ADF with an exposed cog and share a motor with something else. I have a 6000-series printer of the same lineage we got ~10 years ago, and it's been fairly dependable. We use a refill kit and just ignore HP's whiny messages about ink. 😁 Looking forward to your analysis of the scan head! 👍️
If you're a woodworker, old flat-screen displays usually have a nice piece of flat thick plastic that are great for making custom base-plates for your trim router.
I took apart a low end Epson multi function printer a few years ago, and the most fun part was the scanner light. The light want less but something like a mini neon light type system connected to the light bulb was a module which took an input of 12v or so DC, and the output was several thousand volts AC. This was useful to use with the light as is, or, you know, to use the high voltage part for other uses. The ink cleaning system was similar to this, though. There was a kind of scruffy thing that would run against there print head to clean it, and a little pump to pump the water ink into a very thin rubber tube. The and if the tube was just trapped to like a cotton pad ATA random place in the printer. No box, no sensor, nothing.
Dave, I know you say that the surface mount components are pretty worthless, but I disagree. I'm a disabled Air Force Veteran in the US & I am barely living on the just under $300 per month in disability compensation, and since I went from homeless to living in low-income housing back in 2015, all of those are good to me. I have nothing and can't afford much, so I would take the time to desolder them so I could have an assortment of components to work with. It's mainly a hobby but really love doing this kind of stuff, electronics and repairs. I know it's not for everyone but when you can't afford to buy tools and other equipment for repairing and testing electronics you'll get whatever you can however you can. So, just saying that they aren't worthless to everyone.
For $30 CAD, I bought a kit that includes 60 ml of ink for each color, 120 ml of black, and the accessories required to refill the cartridge. I refill my HP cartridges. It's been a year and it's paid for itself 4 times over.
@@rockapartie THE FINGERS! i know exactly what you're talking about. When i refill, i keep a piece of printer paper under it. and i have a lovely colorful painitng underneath when i'm done
River of slime? Yes, I think I saw that twice on your second channel. This thing is meant to be thrown away when shit happens; no expensive parts or stellar engineering here. Speaking of which, I absolutely admire HP for their test equipment (scopes, generators, frequency meters, spectrum analyzers whatnot) - these are absolutely gorgeous and a joy for ever.
@@craigjensen6853 They've _literally_ been different companies for over 20 years. Even their cheap home printers from back then are much better built than then these supposedly office-grade modern units.
21:00 pretty sure that’s a small vacuum pump used both for initial priming of the heads, as well as for routine cleaning to clear clogs. The waste ink receptacle (originally called the “spittoon”) is indeed just a bin with absorbent material. The only inkjets I know of that have actual waste ink tanks (i.e. without sponges) are high-volume inkjets like poster printers, continuous-web printers (yes, your bank statements and utility bills, as well as lots of packaging are now inkjet printed in volume), some high-volume office inkjets, and the old Iris continuous-ink inkjets (which used page-wide nozzle arrays driven by ultrasonic actuator to create a non-stop curtain of tiny droplets, then used electrostatic deflection to direct unneeded droplets into the waste ink gutter and into a waste tank, while the wanted droplets continued unimpeded onto the paper; those printers, which were used for fine art prints and publishing proofs, threw out far more ink than ever made it onto the paper, but did 1800dpi back in the days when desktop inkjets topped out at 360dpi…).
I highly recommend the Epson EcoTank Inkjet printers. The printers aren't super cheap, but they have tanks that accept ink from bottles - so the ink is relatively cheap, and there is no DRM, etc.
A fixed toothed track isn't going to stretch or break like a toothed belt. A better solution as long as you can make the motor light and powerful enough on the moving carriage
I remember taking a similar (Epson) machine apart many years ago. I was just a kid (not that I would fare much better now for this task) so, when I put it back together, I got some 20 screws left!
This sort of PSU, and ones like it, are good for powering those little buck adjustable thingies with a simple UI to make a mains powered adjustable 'bench' supply for kids or novices. 32 Volts gives enough headroom and 30 odd Watts will deliver quite a bit at 3.3, 5, or 12 Volts.
If you just want those voltages get a PC PSU. Short green to ground to turn it on. Ideally you get an older one with blue and white wire, the do -5 and -12V too. I have one with colorcoded banana jacks and USB A ports mounted into the metal case
@@bene5431 While I take your point that a PC PSU makes a good (and cheap) bench PSU - with awsome power capability. A little PSU and a controller make for a smaller, more manageable, form factor. Similar things can also be made with unloved laptop PSUs.
Thanks for saving me the effort. I still have a printer/scanner which I scored from the footpath; I only took it so I could use the scanner once for tax time.
I have a brother inkjet here that is dead. Well...the only thing dead is the touch screen, but it is totally inoperable without a working touchscreen. Can't find a replacement anywhere. Lets see what I can salvage.
Older ones used to be for the stepper motors used for head position... but now days, I agree, junk. The only inkjet I'd ever want would be a large format printer... laser on everything else!
@@ratdude747 After executing the above model (was very satisfying after all the trouble it gave me); I recently got a thermal printer for shipping labels because that's 99% of my printing needs.
@@ratdude747 I took apart one of those large format printers it had 6 really damn strong 120mm blower fans in it plus really beefy motors and even a computer inside with 64mb of ddr1 sodium sadly some proprietary RISC something or other so no repurposing it easily as a mini dos PC or something
@21:20 the white motor with orange rubber baby buggy bumpers, is a pretty strong pump, I think it is for generating a vacuum when the print heads are cleaned and the heads are slurrrrped clean. Strong motor with impeller, forces a strong jet of water, very tight seals. KEEP IT AND MAKE SOMETHING DANGEROUS!!
HELL YEAH, MY MAN! So far I have found that the liquid needs to be a bit thicker than waterotherwise it will dribble and bring the flame to the pump. Am exp. with a bit of laundry deterg w/ 91% isoprop. Oh, and the tiip of the tube (not using a noxxle since fluid is thick) has to be sooo smoothed off. like 3000 grit smooth. liquid too thisck causes air bubbles in impeller which causes other probs. In case you were wondering, ya know for academic interests 'n all that. good luck.
what nope?..... its dope. its a score. them power supplies go virtually forever with polymer caps and a few drilled speedholes. crack em open in a vice. i always cut off the stupid blue RFI supression capacitor off the PCB though.
I've only pulled the little screens with buttons, the guidance rods, and the little switches. Nothing useful. The larger commercial ones I take the stepper motors, rods, the lasers, and the button boards.
I think there's a BS patent on that transparent ribbon with black lines that helps with head positioning, which stops 3D printers from being more accurate on their movements. No idea when it expires, but I heard about it around 2013 or something.
The most useful stuff is the glass, it's A4 size and is a good replacement for a broken glass frame. And that's all. Maybe screws, i keep screws so when I loose one there's good chance to have the good sized one in these crap.
By the way: you don't need to buy brand cartriges. To save money just buy refillables or ciss system and ink for a lot less money. Chinese have hacked those printer chips long time ago.
Consumer-grade printers are so depressing. 99% will only print a few thousand pages in the device's lifetime, meanwhile costing an insane amount of money per page, getting low quality prints, and wasting a ton of plastics and materials. It's convenient to have a printer at home, but it's also one of those luxuries that we could probably do without. Further, we understand that the quality is ass and we get our photos printed professionally. I would not salvage parts from a printer, unless I could throw away the remaining parts for free; you're extracting some screws, inductors, motors and you're generating kilograms of waste that you then need to get rid of.
Although the LCD displays look promising, they're usually a lost cause. I've taken apart many printers and the display is always some obscure custom part with absolutely no documentation available, and as a bonus they often put a custom controller IC between the main board and the display itself, which just adds another level of custom communication protocols. If the printer is still working you can hook up a logic analyzer to the LCD interface and try to reverse engineer the protocol, Hackaday recently featured an article about this. The protocols seem to be fairly simple in general (just clock, hsync, vsync and RGB serial or paralel data), but it's just not worth the effort considering that you can get very nice displays on Aliexpress for like $3 with datasheets and rich Arduino library support...
Any reason why a business would use inkjet rather than laser? I've been using a HP multifunction colour laser printer/scanner/fax/copier for years. No clogs, top quality prints, easy to find 3rd party toner cartridges(no DRM!), literally hundreds of pages between cartridge changes, no waste ink cleaning the heads.
Hi Dave, I'm your subscriber from Ukraine and I've been watching your videos since the beginning of your channel (from way back when I was learning Op-Amps at my university). I really enjoy your blog even though I almost don't work with electronics now (even as a hobbyist). Right now my country is under russian military invasion and we would greatly appreciate if you spread the awareness about it to your audience. Your channel is quite global and I think that even lots of those smart russian engineers who actually designed and developed all those russian missiles and electronics for military equipment are also watching you. I remember that you've mentioned quite a few times that you worked for military and you might be very familiar with the dilemma of end user and application of your intelectual work. We are actually very greatfull for the support by the australian government and that australian media are doing a good job in covering the situation, but your audience is more international (and maybe more influential in the real world) and even small mentioning will help. Thanks.
I've slaughtered like 100 of these, both Inc and Laser, I got loads of motors of all sorts, sensors etc. The one thing I really want to know, is there a chance to use these displays in some of them, if so how can I tell.
No good! Should make the printer changed so that it unscrews other dead printers and reprints their plastics w. structural color and reverses all the microcontrollers to new purpose. Definitely have it make pleasant and mellifluous sound instead of grating inkjet ones. Maybe they can print out gutter leaf guards in the worst case; or siding full of little control panels and pulleys to train magpies to work in mining, I dunno
Before watching this, I'm gonna say there's pretty much nothing worth salvaging in these things. Maybe belts, steel rollers, and the display, but there's really not much there.
why are printers always so stubborn also i attached a brand new hp printer which was dead on arrival to my bike and went riding untill the glass exploded

This kind of e-wasting should be made just as illegal as the #@! DRM on those cartridges. Force the manufacturers to open standardise the ink cartridges themselves or be denied sales throughout the EU.
Inkjet printing technology is incredibly wasteful even by itself. The heads need to be washed and wiped regularily (with the same ink of course as there is no otger liquid in the printer available to do that) and then the ink dries up again and another cleaning is required. Even if you do color prints on a daily basis then having an inkjet printer is just barely justifiable and it is a complete insanity otherwise. Laser printers are just much better in every respect. You can leave one on your shelf for a year and then you turn it on and it just prints straight away with no extra time or consumables wasted. And the cartridges may last for years depending on how often and how many pages you need to print. The only real downside to them is the toner, the nasty tiny colored plastic particles most of which don't get used by the printer and slowly but inevitably find their way out of the printer and then fly everywhere in your room. But that is a very minor issue, overall the technology is much better, there is just no contest.
Even better, make the brains standardized and upgradable. Or at the very least keep up driver support. My daily driver printer is an ancient LaserJet 1022 that I got for $5, works perfectly in Linux using the open source drivers but of course doesn't work at all in more consumer OSes.
@@spagamoto We don't really need standard brains, just a universal standardized printing data format, a standard printer exchange protocol and universal drivers available for most popular OS-s would be enough. You would just look for a label on the box with something like "100% UniPrint std. compatiable" on it and know that with the device at least all the software stuff is not going to ever create any issues for you. I am not sure though that this is any more realistic scenario than having just a single or 2 printer controller PCB manufacturers for all our printers...
In that case the open standard should be done in a way that won't prohibit attaching an auto-refill system or practice of refilling cartridges in general
@@aleksandertrubin4869 That is a separate problem that would probably be outside of scope of a printing data exchange standard that would only focus on insuring complete software compatiability with any personal computer or any other possible source of printing data (cash registers, industrial controllers, et.c.). This DRM crap is something only government regulation can truely eliminate. Or a universal controller like already proposed in the messages above can try to fight it to some extent but I would not count on that anytime soon.
Recently did this with my own similar model HP multifunction printer and was likewise disappointed with the results. I also kept some of the larger flat plastic panels thinking they might be useful. But yeah, mostly garbage. Crying shame these are disposable devices these days. Cheaper to just buy a new printer instead of new ink cartridges. More landfill waste.
@@raiden72 but the brother mfc cost a fortune to run, never getting another one after the last one. Ink tanks are the way to go heaps cheaper than toner on a lazer

@@raiden72 ink tank printers look them up, you buy ink by the litre not the milli litre.

I had so much shit with this HP printer that ended up gaslighting me with its firmware that somehow made the printheads all behave as if their perfectly good nozzles were fecked up by my use of aftermarket inks I smashed it to pieces and threw it in the dumpster. HP are the worst company on the planet and piss on the grave of the founders.
Not only HP, even Epson is able to do suicide after it realises that someone put aftermarket ink it. It was not your fault, these things are supposedly made to fuck self up. And you cannot reverse this by obtaining fresh "original" inks... It stays ducked* forever. Sadly.
@@MartinNyxel Been there myself. I was able to restore it by replacing the print heads. The printer was fine otherwise, so I avoided binning the whole thing. Still borderline evil product design.

Hi again Dave. Thanks for another vid :-) A few motors, power supply, IR sensors, maybe a couple of belt or springs.. they are fab for the parts draw. But what i love most about disassembly, is the dfisassembly itself. Cutting and gutting get understanding how, and what, the things are made and of. Those tranport bars / linear rails, are really handy. They heavy, well balanced, perfectly smooth and resonably strong. I'd use those (after a bit of shaping, not welding it'd just make them too twistable) for extending the reach of drill type screwdrivers/nut spinners.
those steel rods and gears are nice to have. Cold cathode tubes still sell for a lot. I salvaged a printer recently, and one of the parts from the scanner was $78 on ebay. Just those parts you salvaged are easily $20-40 and for a young hobbyist well worth it. In theory, it should have everything needed to build a 3d printer except for the extruder.
You can't build a 3d printer with inkjet parts, i've tried and the 7.5 deg/step steppers that you find in these are terrible. Maybe if you use leadscrews and not belts (like i did) but even then those steppers are only good for full steps because they absolutely hate microstepping or even half-stepping.

Disassembled in Australia! Well played - made me rewind to check it.
A friend has around 12 working laser printers that he salvaged from dumpsters. He has both A4 and A3 printers. He said that most only required minimum repairs to get them working.
A good laser is the bomb. Always ready, very little fuss.
I salvaged a color laser printer, I haven't figured out how to fix the one issue it has, it adds magenta streaks when printing in color, bit t at least grayscale is perfect
@@virtualtools_3021 This may mean at best some cleaning is required or at worst a new magenta toner. See e.g. Brother USA answer 59825 for some hints that may apply to yours as well.
@@virtualtools_3021 Is it possible to print with only the black toner?
I've found one color laser Xerox printer which is complaining for two colors that are low on toner. Black has enough though.
@@worroSfOretsevraH on mine I set it to greyscale on the printer's own menu
Really depends on your goals. For miniature and sculpture work, they're a treasure trove of odd bits!
Have to wonder how many hundreds of dollars of ink is in that waste area, probably several full cartridges of each color. That little vacuum pumps job is to suck your expensive ink out in the name of "cleaning". I gave up on inkjets a bunch of years ago, I only print a few pages a month but was going through several ink cartridges a year. They either dry out or get used up by the periodic cleaning the printers do. What I have saved on ink over several years is now more than what I paid for a color laser and I'm still on the toner that came with the printer. Now when I go to print it just works every time even if I haven't printed in a month.
I’ve seen some printers with ink dumps that where COMPLETELY full of sludge, to the point where it was nearly overflowing and you cannot see the sponge. This is where your ink goes!
The glass scanner bed can come in handy too! I used one as bed for a 3d printer for awhile, and used a glass cutter to make small covers for windows on other projects.
Edit: save all the gears too if you're into robotics!
The leds on the back of the lcd are probably for touch sensing, two sides populated by ir emitters, two sides populated by photodiodes.
That light pipe off the scanner with it's attached RGB LED... if you get several of them you can make some interesting light feature/displays
Also the encoder tape and discs are pretty high resolution, they also usually come with a quadrature sensor which means you can determine direction as well as distance.
I reuse wiring harnesses all the time. Plastic gears and little motors are keepers from printers.
Watch the E-recycle videos on YT to see HP printers in their native habitat.
Printer technology: where the machine is a consumable like the paper it prints on.
Dave, thanks for doing the teardown on this! I work on these from time to time, but mainly the drafting plotters. The HPs are much more technician friendly than other brands. The unidentified motor and pump head supplies vacuum to prime and clean the printhead. The waste ink goes into the spittoon, where the foam is. Despite their pedestrian use, there's quite a bit of engineering inside. Maybe I missed the part where you found the scanner cameras? They're worth as much alone as the rest of the printer. Carry on!
The sponge is called a spittoon. This is used in cleaning the print head. Yes, they mess all over the place. My old Epson Photo 1800 has a microprocessor that stops the printer after printing X 1000 number of sheets to replace the said spittoon. When my printer locked out, The troubleshooter on the website said there were no spittoons left and they will discontinue the ink cartridges for this model. The reset disk cost a pretty penny to reset the micro to resume printing. Cheaper to buy an new one and pay the exorbitant dollars to buy the new cartridges.
This was an interesting video for me, mainly because I've scrapped 10s of printers for parts. The motors, sensors, springs, and metal rods are my favorite things to collect from them.
Depending on the specific vintage of this printer, there may be an additional motor in the automatic document feeder (ADF) in the (edit: scanner) lid. Some of the newer/cheaper ones actually drive the ADF with an exposed cog and share a motor with something else. I have a 6000-series printer of the same lineage we got ~10 years ago, and it's been fairly dependable. We use a refill kit and just ignore HP's whiny messages about ink. 😁 Looking forward to your analysis of the scan head! 👍️
If you're a woodworker, old flat-screen displays usually have a nice piece of flat thick plastic that are great for making custom base-plates for your trim router.
I took apart a low end Epson multi function printer a few years ago, and the most fun part was the scanner light. The light want less but something like a mini neon light type system connected to the light bulb was a module which took an input of 12v or so DC, and the output was several thousand volts AC. This was useful to use with the light as is, or, you know, to use the high voltage part for other uses.
The ink cleaning system was similar to this, though. There was a kind of scruffy thing that would run against there print head to clean it, and a little pump to pump the water ink into a very thin rubber tube. The and if the tube was just trapped to like a cotton pad ATA random place in the printer. No box, no sensor, nothing.
Office Space still has the best way to deal with them.
Dave, I know you say that the surface mount components are pretty worthless, but I disagree. I'm a disabled Air Force Veteran in the US & I am barely living on the just under $300 per month in disability compensation, and since I went from homeless to living in low-income housing back in 2015, all of those are good to me. I have nothing and can't afford much, so I would take the time to desolder them so I could have an assortment of components to work with. It's mainly a hobby but really love doing this kind of stuff, electronics and repairs. I know it's not for everyone but when you can't afford to buy tools and other equipment for repairing and testing electronics you'll get whatever you can however you can. So, just saying that they aren't worthless to everyone.
The holes not being at the ends of the liner rod are to stop harmonics being generated along the whole rod.
For $30 CAD, I bought a kit that includes 60 ml of ink for each color, 120 ml of black, and the accessories required to refill the cartridge. I refill my HP cartridges. It's been a year and it's paid for itself 4 times over.
If it ever gives you trouble next time for laser
@@rockapartie THE FINGERS! i know exactly what you're talking about. When i refill, i keep a piece of printer paper under it. and i have a lovely colorful painitng underneath when i'm done
To this date, the PCB designers fail to communicate with the case designer in my company.
River of slime? Yes, I think I saw that twice on your second channel.
This thing is meant to be thrown away when shit happens; no expensive parts or stellar engineering here. Speaking of which, I absolutely admire HP for their test equipment (scopes, generators, frequency meters, spectrum analyzers whatnot) - these are absolutely gorgeous and a joy for ever.
Yeah, HP Pro stuff is great. Consumer stuff is junk. They are basically two different companies now.
@@craigjensen6853 They've _literally_ been different companies for over 20 years. Even their cheap home printers from back then are much better built than then these supposedly office-grade modern units.
21:00 pretty sure that’s a small vacuum pump used both for initial priming of the heads, as well as for routine cleaning to clear clogs. The waste ink receptacle (originally called the “spittoon”) is indeed just a bin with absorbent material. The only inkjets I know of that have actual waste ink tanks (i.e. without sponges) are high-volume inkjets like poster printers, continuous-web printers (yes, your bank statements and utility bills, as well as lots of packaging are now inkjet printed in volume), some high-volume office inkjets, and the old Iris continuous-ink inkjets (which used page-wide nozzle arrays driven by ultrasonic actuator to create a non-stop curtain of tiny droplets, then used electrostatic deflection to direct unneeded droplets into the waste ink gutter and into a waste tank, while the wanted droplets continued unimpeded onto the paper; those printers, which were used for fine art prints and publishing proofs, threw out far more ink than ever made it onto the paper, but did 1800dpi back in the days when desktop inkjets topped out at 360dpi…).
I highly recommend the Epson EcoTank Inkjet printers. The printers aren't super cheap, but they have tanks that accept ink from bottles - so the ink is relatively cheap, and there is no DRM, etc.
Power supply made by Chicony in beautiful Suzhou, China (the Korean safety marking usually has the actual manufacture listed)
A fixed toothed track isn't going to stretch or break like a toothed belt. A better solution as long as you can make the motor light and powerful enough on the moving carriage
At work i made a voltage reference with zener diodes up to 30V with a HP power supply with 32V.
You can still use one of these as a scanner, if the heads are badly clogged
The ink cartridges usually clog and dry out before they are empty. Lasers last forever so it takes years before you need to replace the cartridge.
I've taken apart a good dozen of those. I use the glass for my 3D printer bed. Cut and sand the edges with emery cloth.
I remember taking a similar (Epson) machine apart many years ago. I was just a kid (not that I would fare much better now for this task) so, when I put it back together, I got some 20 screws left!
I think you missed the feed motor from the lid for the scanner
The glass is really useful for odd projects.
Hi Dave. The little pump could be of some utility to make a motorbike automatic chain oiler
This sort of PSU, and ones like it, are good for powering those little buck adjustable thingies with a simple UI to make a mains powered adjustable 'bench' supply for kids or novices. 32 Volts gives enough headroom and 30 odd Watts will deliver quite a bit at 3.3, 5, or 12 Volts.
If you just want those voltages get a PC PSU. Short green to ground to turn it on. Ideally you get an older one with blue and white wire, the do -5 and -12V too. I have one with colorcoded banana jacks and USB A ports mounted into the metal case
@@bene5431 While I take your point that a PC PSU makes a good (and cheap) bench PSU - with awsome power capability. A little PSU and a controller make for a smaller, more manageable, form factor. Similar things can also be made with unloved laptop PSUs.
Thanks for saving me the effort. I still have a printer/scanner which I scored from the footpath; I only took it so I could use the scanner once for tax time.
25:12: Oh no, you missed the speaker 😀
I have a brother inkjet here that is dead. Well...the only thing dead is the touch screen, but it is totally inoperable without a working touchscreen. Can't find a replacement anywhere. Lets see what I can salvage.
The problem is, is that that there are a million of these per photo copier or industrial sized printers, making the latter way to hard to find.
Can confirm these printers in particular are good for nothing but target practice
Older ones used to be for the stepper motors used for head position... but now days, I agree, junk. The only inkjet I'd ever want would be a large format printer... laser on everything else!
@@ratdude747 After executing the above model (was very satisfying after all the trouble it gave me); I recently got a thermal printer for shipping labels because that's 99% of my printing needs.
@@ratdude747 I took apart one of those large format printers it had 6 really damn strong 120mm blower fans in it plus really beefy motors and even a computer inside with 64mb of ddr1 sodium sadly some proprietary RISC something or other so no repurposing it easily as a mini dos PC or something
@21:20 the white motor with orange rubber baby buggy bumpers, is a pretty strong pump, I think it is for generating a vacuum when the print heads are cleaned and the heads are slurrrrped clean. Strong motor with impeller, forces a strong jet of water, very tight seals. KEEP IT AND MAKE SOMETHING DANGEROUS!!
Flame thrower pump hell yes
HELL YEAH, MY MAN! So far I have found that the liquid needs to be a bit thicker than waterotherwise it will dribble and bring the flame to the pump. Am exp. with a bit of laundry deterg w/ 91% isoprop. Oh, and the tiip of the tube (not using a noxxle since fluid is thick) has to be sooo smoothed off. like 3000 grit smooth.
liquid too thisck causes air bubbles in impeller which causes other probs. In case you were wondering, ya know for academic interests 'n all that. good luck.
Lol, I thought the same thing, but I still rip out all the good parts before I trash it.
Well.... with the momentary chip shortage, thats roughly 2.600 $ in parts....
Mabuchi makes decent power tool motors also.
I always keep printer caps they're usually nichicons or at least elna/panasonic
Generally i always save japanese caps. They are very resiliant
what nope?..... its dope. its a score. them power supplies go virtually forever with polymer caps and a few drilled speedholes. crack em open in a vice.
i always cut off the stupid blue RFI supression capacitor off the PCB though.
I just took apart an inkjet printer and have a box full of plastics. Can it be put in the plastic recycle bin?
Considering I have multiple orders outstanding for electronics components (going on nearly a year now) are you sure it is not worth it...
I've only pulled the little screens with buttons, the guidance rods, and the little switches. Nothing useful.
The larger commercial ones I take the stepper motors, rods, the lasers, and the button boards.
I think there's a BS patent on that transparent ribbon with black lines that helps with head positioning, which stops 3D printers from being more accurate on their movements.
No idea when it expires, but I heard about it around 2013 or something.
Hi, It would help me a lot if you made a vídeo explaining the CAN protocol and how to read the frames with an oscilloscope.
Thanks !!!!! Pleaseeeee
I salvaged one for an over-sized A3-sized scanner bed.
The most useful stuff is the glass, it's A4 size and is a good replacement for a broken glass frame.
And that's all. Maybe screws, i keep screws so when I loose one there's good chance to have the good sized one in these crap.
This video here explains very well why I use a laser printer....
Probably several hundred dollars of ink that's dribbled down over the years
By the way: you don't need to buy brand cartriges. To save money just buy refillables or ciss system and ink for a lot less money. Chinese have hacked those printer chips long time ago.
The clones just make the printer die faster.
Is there anywhere that buys in scrap plastic waste ( metals etc removed from it ?)
Consumer-grade printers are so depressing. 99% will only print a few thousand pages in the device's lifetime, meanwhile costing an insane amount of money per page, getting low quality prints, and wasting a ton of plastics and materials. It's convenient to have a printer at home, but it's also one of those luxuries that we could probably do without. Further, we understand that the quality is ass and we get our photos printed professionally. I would not salvage parts from a printer, unless I could throw away the remaining parts for free; you're extracting some screws, inductors, motors and you're generating kilograms of waste that you then need to get rid of.
Steel rods = good for knife steel?
Although the LCD displays look promising, they're usually a lost cause. I've taken apart many printers and the display is always some obscure custom part with absolutely no documentation available, and as a bonus they often put a custom controller IC between the main board and the display itself, which just adds another level of custom communication protocols. If the printer is still working you can hook up a logic analyzer to the LCD interface and try to reverse engineer the protocol, Hackaday recently featured an article about this. The protocols seem to be fairly simple in general (just clock, hsync, vsync and RGB serial or paralel data), but it's just not worth the effort considering that you can get very nice displays on Aliexpress for like $3 with datasheets and rich Arduino library support...
Yes, i agree with you.
I've taken apart some printers and never find any datasheet for lcd module.
well, you did get a lot of screws and wires/cables out of it.
Maybe even Standoffs??
Well, not really exciting...
No one else noticed "Disassembled in Australia' sticker at 2:23?
Any reason why a business would use inkjet rather than laser? I've been using a HP multifunction colour laser printer/scanner/fax/copier for years. No clogs, top quality prints, easy to find 3rd party toner cartridges(no DRM!), literally hundreds of pages between cartridge changes, no waste ink cleaning the heads.
I have an HP 8600 destined for the trash. I don't think I'll be taking it apart.
Lexmark sells printers worth less than their cartridges.
Hi Dave, I'm your subscriber from Ukraine and I've been watching your videos since the beginning of your channel (from way back when I was learning Op-Amps at my university). I really enjoy your blog even though I almost don't work with electronics now (even as a hobbyist). Right now my country is under russian military invasion and we would greatly appreciate if you spread the awareness about it to your audience. Your channel is quite global and I think that even lots of those smart russian engineers who actually designed and developed all those russian missiles and electronics for military equipment are also watching you. I remember that you've mentioned quite a few times that you worked for military and you might be very familiar with the dilemma of end user and application of your intelectual work. We are actually very greatfull for the support by the australian government and that australian media are doing a good job in covering the situation, but your audience is more international (and maybe more influential in the real world) and even small mentioning will help. Thanks.
I've slaughtered like 100 of these, both Inc and Laser, I got loads of motors of all sorts, sensors etc.
The one thing I really want to know, is there a chance to use these displays in some of them, if so how can I tell.
Why, just why you did'nt keep the gears, you engineer ? You can reuse it in robotic or model-making project...
think you missed a small speaker
Intriguing!!!
Wow, an actually legitimately broken device.
No good! Should make the printer changed so that it unscrews other dead printers and reprints their plastics w. structural color and reverses all the microcontrollers to new purpose. Definitely have it make pleasant and mellifluous sound instead of grating inkjet ones. Maybe they can print out gutter leaf guards in the worst case; or siding full of little control panels and pulleys to train magpies to work in mining, I dunno

I have one HP 8710 working.
Why are so many printers in the garbage? Because it's cheaper to buy a new printer than it is to buy more ink.
Before watching this, I'm gonna say there's pretty much nothing worth salvaging in these things. Maybe belts, steel rollers, and the display, but there's really not much there.
Jesus! There is about £80k of ink in that sponge.

It depends on what the interface is. They usually run from 3.3v and often use USB as an interface. SDIO might also be common.
Thanks!
These things really are a disgrace and should be ground out of existence.
I honestly think you get more fun out of tearing it apart than the value of the parts.
17:31 Could it be used to increase accuracy of 3D printers?
Given the price of printer ink... that sponge is worth its weight in gold. 😜
This kind of e-wasting should be made just as illegal as the #@! DRM on those cartridges. Force the manufacturers to open standardise the ink cartridges themselves or be denied sales throughout the EU.
Inkjet printing technology is incredibly wasteful even by itself. The heads need to be washed and wiped regularily (with the same ink of course as there is no otger liquid in the printer available to do that) and then the ink dries up again and another cleaning is required. Even if you do color prints on a daily basis then having an inkjet printer is just barely justifiable and it is a complete insanity otherwise.
Laser printers are just much better in every respect. You can leave one on your shelf for a year and then you turn it on and it just prints straight away with no extra time or consumables wasted. And the cartridges may last for years depending on how often and how many pages you need to print. The only real downside to them is the toner, the nasty tiny colored plastic particles most of which don't get used by the printer and slowly but inevitably find their way out of the printer and then fly everywhere in your room. But that is a very minor issue, overall the technology is much better, there is just no contest.
Even better, make the brains standardized and upgradable. Or at the very least keep up driver support. My daily driver printer is an ancient LaserJet 1022 that I got for $5, works perfectly in Linux using the open source drivers but of course doesn't work at all in more consumer OSes.
@@spagamoto We don't really need standard brains, just a universal standardized printing data format, a standard printer exchange protocol and universal drivers available for most popular OS-s would be enough. You would just look for a label on the box with something like "100% UniPrint std. compatiable" on it and know that with the device at least all the software stuff is not going to ever create any issues for you.
I am not sure though that this is any more realistic scenario than having just a single or 2 printer controller PCB manufacturers for all our printers...
In that case the open standard should be done in a way that won't prohibit attaching an auto-refill system or practice of refilling cartridges in general
@@aleksandertrubin4869 That is a separate problem that would probably be outside of scope of a printing data exchange standard that would only focus on insuring complete software compatiability with any personal computer or any other possible source of printing data (cash registers, industrial controllers, et.c.).
This DRM crap is something only government regulation can truely eliminate. Or a universal controller like already proposed in the messages above can try to fight it to some extent but I would not count on that anytime soon.
Recently did this with my own similar model HP multifunction printer and was likewise disappointed with the results. I also kept some of the larger flat plastic panels thinking they might be useful. But yeah, mostly garbage. Crying shame these are disposable devices these days. Cheaper to just buy a new printer instead of new ink cartridges. More landfill waste.
Brother MFC laser color printers last absolutely forever, invest once and then you will save much frustration down the line!
@@raiden72 but the brother mfc cost a fortune to run, never getting another one after the last one. Ink tanks are the way to go heaps cheaper than toner on a lazer
@@patty4730 anyone that's ever had an inkjet printer for more than one year knows that the ink dries out over a couple months and you have to keep buying ink every single year.

@@raiden72 ink tank printers look them up, you buy ink by the litre not the milli litre.

@@patty4730 "Yes, it is a lot more work to maintain than a laser printer. The heads need LOTS of cleaning way too often, but the printers deliver."

Took an older HP ink jet apart some years ago.

Good point. I need some gears.
Those leds around screen are actually IR leds and IR detectors used to detect finger pressing the screen. It detects position of finger by x an y beams are interrupted. Plastic around screen is used then to direct those beams acros the screen.
Totally missed that. That makes sense.
That's the OLD school way of doing it. Surprised it's not cheaper to just use a digitizer given how ubiquitous touch LCD panels are now.
Oh so that's why they're so shit.
just like the kindle
I had so much shit with this HP printer that ended up gaslighting me with its firmware that somehow made the printheads all behave as if their perfectly good nozzles were fecked up by my use of aftermarket inks I smashed it to pieces and threw it in the dumpster. HP are the worst company on the planet and piss on the grave of the founders.
Not only HP, even Epson is able to do suicide after it realises that someone put aftermarket ink it. It was not your fault, these things are supposedly made to fuck self up. And you cannot reverse this by obtaining fresh "original" inks... It stays ducked* forever. Sadly.
Even their commercial printing products are junky
The founders were cool guys. Blame the suits that run the company now.
Need a hug?
@@MartinNyxel Been there myself. I was able to restore it by replacing the print heads. The printer was fine otherwise, so I avoided binning the whole thing. Still borderline evil product design.

Hi again Dave. Thanks for another vid :-) A few motors, power supply, IR sensors, maybe a couple of belt or springs.. they are fab for the parts draw. But what i love most about disassembly, is the dfisassembly itself. Cutting and gutting get understanding how, and what, the things are made and of. Those tranport bars / linear rails, are really handy. They heavy, well balanced, perfectly smooth and resonably strong. I'd use those (after a bit of shaping, not welding it'd just make them too twistable) for extending the reach of drill type screwdrivers/nut spinners.
That's the main reason I do it 🤠
those steel rods and gears are nice to have. Cold cathode tubes still sell for a lot. I salvaged a printer recently, and one of the parts from the scanner was $78 on ebay. Just those parts you salvaged are easily $20-40 and for a young hobbyist well worth it. In theory, it should have everything needed to build a 3d printer except for the extruder.
You can't build a 3d printer with inkjet parts, i've tried and the 7.5 deg/step steppers that you find in these are terrible.
Maybe if you use leadscrews and not belts (like i did) but even then those steppers are only good for full steps because they absolutely hate microstepping or even half-stepping.
Do they *sell* for a lot or just *list* for a lot though? lol
