    Re: MAGENTA out of focus

    have you cleaned the registration sensors for image the do an inialize and reset then gradation. i have ony ever had to do a skew adjustment and that was on a c652 once. if the others fail then it might be laser units or printheads which ever do desire to call it. start with the easy stuff first.

    P21 is either stabilization problem OR Color Registration Problem. Please try following

    Replaced Drum, Developer Or ITB Unit ( known working Used one will do, Just for trial & eliminating problem Cause).
    If this fails, only option is to replaced PH unit. If I understand correctly there are two issues in this case one is skew adjustment and another is Magenta shift. Normally registration can be corrected as well as skew as there are 4 Drum units. But when bot are presents mostly it is PH unit or Board.
    Hope this helps
