    So you don't have a developed latent image? It could be the LED array, developer bias, developer agitation, or drum drive.

    I think you can see if the drum and developing unit are turning with the front door keyed, and the inner cover off. The one case of a failed LED array was pretty strange. See here:
    bizhub PRESS 1052, interesting print anomalies

    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.
