2.2.10 Mechanical Drive for Offset
The Offset Motor provides mechanical drive for the Offset Rolls. The
Offset Motor transmits drive to the Offset Bracket. If the printer is
running in Offset mode, the MCU switches on the Offset Motor. The
Motor drives the Offset Bracket toward the front of the printer. The
Bracket pushes the Offset Roll along with it. The Offset Rolls drive one
sheet of paper into the Face Down Output Tray. The MCU switches the
Offset Motor on again, and the Motor drives the Offset Bracket back to
the rear of the printer, taking the Offset Roll with it. The Offset Rolls
drive the next sheet of paper, slightly offset from the last sheet, into the
Face Down Output Tray.

2.2.11 Paper Path Component Control
The logic on the MCU PWB controls the Paper Path components.
Sensors along the paper path monitor the movement of each sheet of
paper and send information back to the MCU. The MCU provides the
timing and data processing necessary to actuate clutches and
solenoids, switch motors on and off, and to identify paper jams. The
MCU PWB provides the +24VDC drive signals for the Main Motor, the
Offset Motor, and the assortment of clutches and solenoids within the
printer. The MCU PWB also pr5VDC to the paper path sensors.
