Re: oki es3640e major printing faults
ok, thanks. I tried it and it wouldn't get past communication error, I thought it would work, in theory. Unless I have two broken main boards, which is a possiblity.

Re: oki es3640e major printing faults
If I used the main board from the c9800 and put the HDD and the eeprom from the es3640 on it, would that work? And not change over the key chip, or anything else?Leave a comment:

Sorry for misleading. Good to know you found the problem.
I was probably misled by the colleague who replaced the Transfer Belt. I hope I can find the samples to upload them here for a opinion.Leave a comment:

If you replaced the main board, then yes, you could fix it. I suspect that you won't be able to repair the damaged board. =^..^=Leave a comment:

Re: oki es3640e major printing faults
It wasn't the transfer belt, I took out the main board and swapped it into a c9800, and now the c9800 prints with exactly the same error - so the problem traveled with the main board, which means it probably isn't something I'm going to be able to fix?Leave a comment:

Re: oki es3640e major printing faults
I had this strange fault and spent hours disassembling and fitting Drum Units, swapped LED units with working ones, replace whole LED ribbon cables, both SYS and Logic boards, Memory module, HDD format, FW updates you name it.
It was the freaking Transfer Belt causing that - 2 min job. I don't know how and why - no explanation I could think ofLeave a comment:

oki es3640e major printing faults
we moved an es3640e that was working fine. After it was moved I tested it and there were big problems, the pages had a solid block of cyan for the background and the magenta running in long bands. I replaced all the drums and toner - same problem though, or similar, the cyan disappeared completely on the second PS test sheet. I've attached a few photos, any ideas on where to start looking?
