    [Error Code] J-3103 on C8000

    Hi folks asking for your help
    I am getting:
    J-3103:
    During operation: The registration sensors /Fr
    (PS1) and /Rr (PS2) do not turn ON within a
    specified period of time after the registration
    motor (M58) turns ON.

    and J-1702:
    During operation: The registration sensors /Fr
    (PS1) and /Rr (PS2) do not turn ON within a
    specified period of time after writing starts during
    back side printing.

    I haved tried, cleaning by vacuuming the area
    Replaced entire registration unit with working one from another machine.
    Replaced entire fusing unit with working one
    Rewrite firmware
    Even replaced EF-101 fuser unit with working one too


    Still getting this problem.
    Any point in your experience guys that may be causing this
    Customer running crazy on me

    Thanks in advance for ur help
