Media Path Drive - Xerox Phaser 8400 Service Manual

Media Path Drive

The media path drive gearbox and motor assembly controls each roller in the paper
transport system. A gear train located behind the motor connects it to the exit rollers,
which are built into the exit module. Gear trains located within the media path drive
assembly, along with two clutches and a solenoid, allow the motor to control the pick,
take away, duplex, and deskew rollers.
A unique swing gear allows the pick roller and take away roller to rotate in the same
direction regardless of the direction the motor is rotating.
