[CE71] Drum phase adjustment abnormality
(1) Is the drum shaft rotating normally? (Perform the output check: 03-110 and 03-111)
(2) Check if the harness or connector of the color drum phase sensor or the K drum phase senor is disconnected or open-circuited.
(3) Is the drum loaded abnormally?
(4) Is the drum motor (K)/(YMC) broken?
(5) Check if the harness or connector of the drum motor (K)/(YMC) is disconnected or open-circuited.
(6) Check if the tooth surface of the transfer belt drive gear is damaged.
