    WC7346 color misalignment

    Hi all,
    I've a 7346 in my hands, with a strange problem. The simptoms are common... color misregistration and streak deletion. This last is not so evident, but obviously the IBT is reaching his end of life. I've runned all the the tests in regi-con, following step by step the service manual procedures (Belt edge learning, fine skew setup, etc etc). The strange thing is that "final result" in every test is "NG", and i can not read the adjustment values (such number of rotations cw or ccw for the KCMY adjustment screws).

    The attachment shows the misregistration problem

    Any idea?

    Thank you all

    At least try cleaning all the mob sensors. They tend to get very dirty.

    SOLVED!

    A good and deep cleaning of all the xerographics and sensors. Values readed correctly and machine has applyed his corrections automatically. The key was the MOB sensor completely covered by toner.
