    Bizhub C452 wierd problem while copying

    I hope someone has had this problem and can help me find the problem.
    Copy quality is fine, printouts and printings too.
    Suddenly for no apparent reason the copies look very bad (see attachment)
    but printouts and printing remain fine.


    It doesn't seem to affect it if you move the machine, open the paper trays, or the document feeder.
    If the copies are good, they stay fine, and if they are bad, they don't make up either.


    What I've done so far:
    Replaced Yellow and black drum units (were at end of its life trowing some warnings)
    I cleaned and vacuumed the copier
    Inspect and cleaned optics
    Inspect and cleaned ADF
    Initialized all settings
    Setup according to installation instructions (prevent lines of shame)
    reinstall all settings


    Machine still doing the same, any help is welcome!


    PS: Copies attached are from a blank original

    I would reseat the cables on the ccd and where they plug into board. If that doesnt resolve your problem you may have a bad ccd

      Thanks for your answer Markks
      checked the connectors and cables twice, everything seems normal,


      I'm going to replace the CCD and post the result.
      If you come up with another ideas, feel free to post them, because I'm running out of ideas.
