    7550ci dirty copies

    Getting black lines on copies/prints - cleaned charge rollers for temp fix, have replaced transfer belt and black drum(had small spots from drum), still waiting on a new fuser, however no physical indication that fuser related to lines but the belt is starting to blister on edges so ordered new fuser to replace.... any suggestions?

    You say that you cleaned the primary charge rollers, and the image quality improved.
    Have you considered replacing the primary charge rollers, and maybe performing a color calibration? It sure seems logical. =^..^=
    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.

      Are you up on your firmware? V.3 update included some measure to prevent "toner dusting". It made some change to the main charge values.
