    3800C

    Hello these days I have on the verso of my copies some traces on the paper, like black or oil...

    any idea ?

    I need also to do too many times a manual adjustment for the shifting of color

    thanks

    Fuser oil has been known to leak over the black PCU which can make things pretty messy.
    The colour reg problem is probably related to ITB requiring a service but leaking oil would also cause a problem there as well.

    - I know what I need to know as I need to know it, but knowing is not enough I must understand what I know.

    You need to confirm if it is a oil leak or not by taking out the fuser, black PCU and ITB unit.

    If there's oil everywhere it's a clean up and damage assessment job.
