    sounds like yellow drum unit needs to be replace . have you pull yellow unit out to see if drum unit is clean and look at how many copies on unit. good only for 120,000 copies

    Replace yellow dev. unit (most common cause), and PCU (if it's towards end of life). If that doesn't take care of it, then you may have a broken wire in the ITB unit (seen it a few times).

    I have seen this with a dirty charge roller. Doesn't show on B/W since the color transfer rollers in the ITB assembly are not engaged.

    if the transfer belt is so dirty, first replace the ITB cleaning unit, the accumulation of so much toner is also the result of incorrect cleaning. If the developer is old, dust everywhere, change it.
