I've given up on the 8300 and the 8400 gets here tomorrow. My machine has either a faulty main board or flex cable (everything else has been replaced). it produces a missing block of yellow and I'm not spending any more $ to figure out why. Both print heads were replaced, so was the pcb and some other bits. The print heads have printed 3 nozzle checks and nothing more and I'll give you original receipts. make an offer on any or all of it and it's yours. I'm just trying to end up with a few bucks to put to the new one. printer is located in Denver.
The print heads must go in another 8300 and on the same L and R sides. I actually have two L heads and one R from all of this trouble shooting.
