Driving force transmission path
Transport motor
The rotating force of the transport motor is transmitted through the gear and the pulley (25 tooth) to components
that need mechanical driving force as shown in the following diagram.
The driving force transmitted to the gear drives the transport roll assembly, multipurpose feeder (MPF) feed roll,
registration roll assembly, fuser assembly, and exit 1 media exit roll assembly through the clutch and gears.
The driving force transmitted to the pulley (25 tooth) drives the exit 1 media exit roll assembly through the gears.
The driving force transmitted to the fuser assembly drives the heat roll.
PC cartridge motor
The rotating force of the PC cartridge motor is transmitted through the gears to components that need a
mechanical driving force as shown in the following diagram.
The driving force transmitted to the PC cartridge drives the drum. The driving force is then transmitted to the
transfer roll assembly by direct contact with the drum.
