    For me, its always been the eight pieces of paper accordianned in the fuser exit, that the enduser doesn't notice. It stops the fuser drive. =^..^=
    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.

    Eight because it's 8 series or because it's bizhub 808

    Re: Bizhub 808

    A simple question, but it can solve:


    Did you perform the trouble reset?
    Nothing like day after day

    Yes, exactly. =^..^=

    Sounds like you've done all the logical steps----- If replacing the fuser unit and fuser motor and then running the trouble reset did not fix the issue, I would suspect something is bad in the fuser drive unit assembly.
