Theory of Operation
■ K Drive Assembly
The transmission channel is changed by the the Color Mode Switching
Solenoid in the K Drive Assembly to allow the driving force of the Sub
Motor to reach the C/M/y Developer only.
This process ensures that the Yellow, Magenta, and Cyan Developers
cannot be rotated by the Sub Drive Assembly during black and white
printing.
