A small follow-up on the Panasonic photocopier teardown, showing the paper feeder tray.

Done.
Man, taking apart a big printer is like slaughtering a cow.
So much delicious meat everywhere!
lol .stepper made in my country XD
please do a teardown of a toshiba estudio copier
Mine was better than yours Dave, I pulled a total of 47 optical sensors out of the Brother, I have enough for the rest of my life and I've been told I have another one coming. Cheers , Billy, Canada
Hi Dave, thanks for all the interesting videos. As a 58 year old newbie to electronics your videos have inspired me to build my own projects, starting with arduino. The component and board descriptions during your tear downs really help to give me new project ideas. I relay dislike all those who put forward negative destructive comments rather than constructive helpful comments to help other viewers. I guess their negativity stems from their own inadequacy. keep up the brill videos please. thanks again Jon c, twickenham, London, england.
Isn't that "linear cog" system called a rack and pinion?
I didn't hear him say, I might just be deaf
what about that intel PC based motherboard you found in the copier? what kind of CPU did it have on it?
do it
paper point, paper point, paper point :))
I have build a transformer and coil winding machine from an old photocopier 😀
Nowadays in my town it is easier to find ancient treasure than to find old matrix printer or 5'25 floppy drive. I even couldn't get old-school voice-fax-modem here when I need it.
Somewhat surprised so see a standard Nema23 stepper being used in this kind of equipment, instead of the cheaper 'tin-can' steppers.
With all those gizmos in a photocopier they are dangerous, they turn into nasty Transformers with the help of Allspark
Total teardowns are good for fun and can yield looots of shafts, ballbearings, brass bearings, photo interrupters, limit swithches (general purpose only, I have not yet salvaged any high precision switches), cabling&connectors, ferrite bead, LCD (often standard modules with drivers, otherwise not usable much), aluminium heatsinks & thermal pads (these are always nice to have). Dave, we know you have increased the weekly video uploads, but any plans to cover more projects, we miss the DIY part.
That's the ADF (automadic document feeder) unit. From the experience, they will usually have the best stepper motors you can salvage from a copier teardown. I've stopped hauling the bulky copiers back to the garage a long time ago, and now I get ADF units instead. It's the most efficient way to go if you have lots of these units and limited time, given that you are after stepper motors (mainly for DIY CNC builds) and dont care about the other "gems".
Yeah… I'm afraid it would be like watching a re-run of the photocopier episode. I actually had Déjà vu watching you tear down that copier… The Konica/Minolta Color Laser printer I dismantled looked like it was born from same set of design files as your copier. The harness techniques, a lot of the hardware, a number of the modules all had a uncanny resemblance. I suppose it could just be typical of nice Made in Japan commercial print gear…

it says 1.3-1.6 mV for the led
not volts
do a GIVEAWAY for the stepper motor 😛
I found the coolest stuff in an OLD box of collator parts! Think Germaniun transistors OLD! All of it was brand new old stock Phoenix Arizona Motorola made stuff. The box was a mass order Motorola never shipped. I think if I took Dave to work with me I'd have to keep him on a leash! He would be trying to tear apart everything in sight.
Sorry, not "chunky commercial", but desktop consumer.
I scored two in the garbage room the other week. Maybe a tear down of those as well?
The sensors are to select an auto enlarge/reduce for the fax side of the machine, so a small document is full size on the receiving end. Changes from none to 3 other according to document size. Also works for the copier side if it is on default of auto then all docs are full size on paper supply. The clip on optoswitched have a separable top, you can pull it off and see the diode and phototransistor inside it in clear packages.
Yeah i racked my pinion once, wont do that again
I wish I could find a junk photocopier to rip the steppers etc out of .. but if I brought anything like that home my wife would kick my head in :/ Are you going to do an overview of the main board? I'm interested to see what was running the show.
Are there any VCRs with stepper motors?
vcrs are goldmines as well
Game consoles are boring. They're just like computer motherboards.
A chunky commercial Laser printer yields just about the same bounty as a copier, but at about 1/3 of the bulk. Your local thrift shop likely has a stack of copiers/printers collecting dust bunnies back in the warehouse. Fun stuff!

there is the main video
