    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?

    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 of

    So if it is the primary transfer belt, Alastair should be able to emergency stop the machine, and see the exact same latent image on the belt ... not a good latent image.

    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

    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?

    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. =^..^=

    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.

    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?

    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.
