I have an old inkjet printer and was taking it apart (an old Lexmark). I looked at the back, and there looks like there is a matrix of copper connections back there. Just tinkering, I took a 9V batter with two wires, and tried touching a few of these pads to see if I could get it to fire....some sputtering, but not much.
Does anyone know about inkjet printers and cartridges? Is there a good website that might help me out (I am googling this idea as well)? I would love to be able to figure out how to make the cartridge fire with some simple electronics (its part of a much bigger curiosity I have festering in my mind)...thanks!
