If nothing else I'd like to find a way to use the little LCD displays out of these printers. I've got four or five in a box from printers I've scrapped & have always wanted to build them into something.
After so much time with a disassembled printer taking up space in my room, and so much time searching for help, I finally saw your thumbnail with some parts that look exactly like the ones I've got. *rubs hands together* time to get down to business
For others... This project will need the help of a logic analyzer (i.e. a BusPirate, or RPi repurposeed as a logic analyzer) in order to identify the communication protocols and pinouts..
Hello Mike, did you figure it out, I've had a control panel touch pad from HP for a while now, and I can not figure it out, my circuit board on the back of the touch pad says CN503 80002 A, but I think the CN503 60002 is the same. look forward to seeing part 2
I am working on Part 2. I have an oscilloscope and tried checking the signals. I can see some interesting signals. But I think I need a logic analyzer.
@@BiffMartin I've been using a cheapo logic analyzer from ebay for this sort of thing. Plenty enough for a homegamer! Mines not even branded! 😂 I've got an lcd from a dead Samsung laser printer on my own bench atm
Hi Mike, curious about part 2. Any progress so far?
where is part2 ?
would love to see that one and do the same on my printer !
Hi Mike, still working on part 2 or did you give up? I would be very interested in things you found out 👍
Me too! Looking forward to part 2 :D
I need to jump back into this subject. Just need to purchase a better oscilloscope or maybe a logic analyzer.

Hello Mike, I have a similar model from HP here, looking forward to seeing part 2 and what your conclusions are. Hope you figure it out!
Yes, sir. More videos are coming.

Any chance for part 2?

part2
If you are not going to continue with part 2 then take down this video. It gives a false result and wastes 6 minutes of our time for nothing.
never going to get my 6 minutes back am I
somebody else might see this and find a solution
