    Heads-up: 7353ci CQ light bands OOB or after service

    This problem has been seen rarely and looks like a DV problem unless you examine U089 grey prints under a loupe.

    It is a Color Registration data issue and can be resolved my resetting the Color Registration Correction adjustment in U467 (below).

    In the effected area and color(s), the dot patterns shift and adjacent lines overlap.

    In U467 Turn Color Regist to OFF
    Power Cycle and perform Automatic Color Registration
    Set U467 Color Regist to ON
    Power Cycle and re-check color registration.

    Thanks! That's a good one. =^..^=
    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.

        The LSU dot pattern was the major clue. I had to think why the pattern would diverge in certain areas and that led to the manual color registration, which has several positions for adjustment values across the page. If one of the areas was applying a gradual increment that the others did not it could mean bad adjustment values.

        Then I remembered the Color Registration problem on the FS-C2126 where the values would not adjust properly until a reset was performed, and the procedure I used was the basic steps from that fix.
