    C552 color registration issue

    Hi Guys

    have a colour reg issue on our C552

    ive followed field manual page 728 (18.3.33 Printer 4-color: incorrect color image registration)

    cleaned transfer belt (although not dirty)
    cleaned transfer roller on door
    fuser is brand new.

    but color reg is off. and its not equally off over the entire page. the Y axis is ok at the start, but completely out at the end.
    see attached pic

    ive attached all the warnings i can find.

    Look for the oil can at the bottom of the screen. If there is one, tap it to display any P codes.

    I had something similar that turned out to be the LPH driver board.

    Means your color imaging units M & Y and K drum are past end of life. Might want to replace those first and go from there.

    It started to happen after replacing the fuser unit

    forgetting those C Y M drums etc. what else can it be?

    I do need to strip down the machine and clean everything. but thats a mission and a half.

    There is a loop sensor just before the fuser entrance that can cause lead to trail color alignment issues.
