    [C022] Developer unit mixer motor-YMC locking error


    (1) Pull out the EPU tray and perform the output check (03-115) to check if the 3 outputs of the YMC developer unit mixer are rotating normally.
    When it is not rotating:
    (2) Is the connector of the YMC-developer unit mixer motor connected securely?
    (3) Check if the harness or connector of the YMC-drum motor is disconnected or open-circuited.
    (4) Check if the YMC-developer unit mixer motor is abnormal.
    (5) Check if the drive gear array has any abnormality such as breakage.
    When it is rotating:
    (6) Check if developer material is excessively supplied to each YMC-developer unit.
    (7) Check if the drive gear array of each YMC-developer unit has any abnormality such as breakage.

      Thank you for your response,
      everything looks fine and running 03-115 does nothing but the developers units movement are free and smooth,
      The original problem was CD81, after cleaning the pipes the CD81 was cleared and pop-ups C022

      Any help is welcome
