    2nd sides are grey through a dual scan ADF (DF702)

    Hi,

    Has anyone had the dual scan PWB go down on a C654e?
    We have a customer with 2 x C654e Bizhubs and we have swapped the complete ADF with cables over, but still get 2nd sides grey, on the original machine. The fault didn't transfer with the adf.
    Raised issue with Konica tech, but not much to go on....

    Thanks,

    Guy

    There is a board that handles the CIS image data ... DSIPB... DISPB? Something like that. It sits right on the MFPB. That's where I would start. =^..^=
    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.

    Replaced the DSI PWB ( Dual Scan ) on Friday. No good, returned today with the same problem.
    Next step is to reset the MFP board with the reset tool. Failing that, the MFP board itself.

    The cable from dual scan board to mfp board ? No, just the board.

    I have had second side image data corruption caused directly by the MFP board before.

    (after absolutely everything else replaced first, it always leads us there eventually)
