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
runnin
g
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 alon
g
with it. The Offset Rolls drive one
sheet of paper into the Face Down Output Tray. The MCU switches the
Offset Motor on a
g
ain, and the Motor drives the Offset Bracket back to
the rear of the printer, takin
g
the Offset Roll with it. The Offset Rolls
drive the next sheet of paper, sli
g
htly offset from the last sheet, into the
Face Down Output Tray.

2.2.11 Paper Path Component Control
The lo
g
ic on the MCU PWB controls the Paper Path components.
Sensors alon
g
the paper path monitor the movement of each sheet of
paper and send information back to the MCU. The MCU provides the
timin
g
and data processin
g
necessary to actuate clutches and
solenoids, switch motors on and off, and to identify paper jams. The
MCU PWB provides the +24VDC drive si
g
nals for the Main Motor, the
Offset Motor, and the assortment of clutches and solenoids within the
printer. The MCU PWB also provides +5VDC to the paper path sensors.
