The drum drive motor-K [A] drives the PCU for black.
The drum drive motor-CMY [B] drives the PCUs for magenta, cyan, and yellow.
Using one motor to drive these three drums reduces CMY color misalignment.
Both motors are brush-less DC motors. This helps to reduce the drive noise. The
brush-less DC motors make sound that is not the same as other machines, but this
sound does not mean machine defective.
