2.1.2.1 Offset Motor
In Offset, printed papers are ejected into either rear side or front side.
Offset Motor
g
enerates the drivin
g
power for Offset pa
g
e eject. Also,
printed papers can be divided by the number of distribution. MCU
switches the Offset Motor on and off, durin
g
the offset paper eject.
1. When MCU(Machine Control Unit) turns on Offset Motor, the Offset
Motor drives the Bracket toward the front of the printer, pushin
g
the
Offset Roll alon
g
with it.
2. When the Bracket reaches the end of travel, MCU stops Offset
Motor.
3. The MCU a
g
ain switches on the Offset Motor, which drives the
Bracket toward the rear of the printer, carryin
g
the Offset Roll alon
g
with it.
4. When the Bracket reaches the end of travel, MCU stops Offset
Motor and eject the paper, leavin
g
the Offset Bracket in that
position.
2.1.2.2 Main Motor and Main Drive Assembly
The MCU PWB switches the Main Motor on and off. The rotation of the
Main Motor creates mechanical drive.
The Main Drive Assembly
g
ears transmit the motor drive to Feed Clutch
1, Feed Clutch 2, and the MSI Feed Clutch. At paper feed, the MCU
PWB actuates a Feed Clutch, which in turn transmits drive to the
appropriate Feed Rolls.
The Main Drive Assembly
g
ears transmit the motor drive to the
Re
g
istration Clutch. At a specific point in each print cycle, the MCU
PWB actuates the Re
g
istration Clutch, which in turn transmits drive to
the Re
g
istration Roll.
The Main Drive Assembly
g
ears transmit the motor drive to the Fuser
Drive Gear. When the Left Upper Cover is closed, the DTS Link Rod
pushes the Fuser Drive Assembly into contact with the Fuser Drive
Gear, which transmits drive to the Fuser Rolls.
The Main Drive Assembly
g
ears transmit the motor drive to the Drum.
When the Main Motor is on, the Drum rotates. When the Left Upper
Cover is closed, the BTR
g
ear contacts the Drum
g
ear, which in turn
rotates the BTR.
The Main Drive Assembly
g
ears transmit the motor drive to the Exit
Drive, which transmits drive to the two Inverter Clutches. At a specific
point in each print cycle, the MCU PWB actuates either the CW Clutch
or the CCW Clutch which drive the Exit Roll and the Offset Roll.
