Driving force transmission path
Media 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.
MPF/transport drive 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 MPF/transport drive motor provides the driving force transmitted to the gear drives, the transport roll
assembly, and the multipurpose feeder (MPF) pick roll.
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.
