DRIVE ASSY PH
DRIVE ASSY PH transmits the driving force from the DRIV ASSY SUB to relevant parts.
The transmission channel is changed by the COLOR MODE SWITCHING SOLENOID in the DRIVE
ASSY PH to allow the driving force of the DRIVE ASSY MAIN to reach the Black Developer only.
This is performed to ensure that the Yellow, Magenta, and Cyan Developers cannot be rotated by
the DRIVE ASSY SUB during B/W printing.
The COLOR MODE SWITCHING SENSOR detects the status of the transmission route (whether it
is set for B/W or full color).
