Drum Drive
[A]: Drum motor
[B]: Drum motor coupling
[C]: Drum shaft
Each PCU (Y, C, M, K) has an independent drum motor.
The drum motor [A] rotates the drum motor coupling [B] and drum motor shaft [C].
During black-and-white copying and printing, only the black drum (K) rotates. The
other color drums (Y, M, C) do not rotate.
The drum shaft must be locked with a special tool attached to the front end of the
shaft in order to remove the drum motor. The special tool is attached to the
bottom of the PCU stand. For more, please refer to Section "3. Removal and
Replacement".
