3.5.1 Major functions
- SENSOR PHOTO (Full Stack Sensor)
Detects that the prints discharged onto the top cover have accumulated more than specified number
of sheets based on the change of position of the actuator.
(Full stack: Sensor beam is received)
- SENSOR PHOTO (Dup Jam Sensor)
Detects that paper has reached and passed through the ROLL DUP based on the change of
position of the actuator.
(Paper present: Sensor beam is received)
- SENSOR PHOTO (MSI No Paper Sensor)
Detects existence or non existence of paper on the manual feed tray based on the change of
position of the actuator.
(No paper: Sensor beam is intercepted)
- MALTIPURPOSE FEEDER (MPF) SOLENOID
Controls the operation (rotation/stop) of MULTIPURPOSE FEEDER (MPF) ROLLER by controlling
the rotations of the GEAR MSI.
- MALTIPURPOSE FEEDER (MPF) ROLLER
When the MALTIPURPOSE FEEDER (MPF) SOLENOID operates, the GEAR MSI and Gear IDLER
are engaged by the force of the SPRING FEED H, the MALTIPURPOSE FEEDER (MPF) ROLLER
starts rotating under the drive from the MAIN DRIVE ASSEMBLY, and feeds paper from the manual
feed tray.
After having rotated one turn, the GEAR MSI and Gear IDLER are disengaged at the notch of the
GEAR MSI, drive is not transmitted any more, and the MALTIPURPOSE FEEDER (MPF) ROLLER
stops rotating. Thus sheets of paper are fed one by one.
- ROLL DUP
The ROLL DUP rotates under the drive from the MOTOR ASSY DUP and feeds paper printed on
simplex returned from the CHUTE ASSY EXIT to the ROLL TURN.
- MOTOR ASSY DUP 17PM
It supplies the driving power to ROLL EXIT and ROLL DUP.
- ROLL EXIT
ROLL EXIT receives the driving power from MOTOR ASSY DUP 17PM and rotates, and transports
the printed paper after fixing onto the top cover.
Furthermore, it rotates reversely, in the case of duplex mode, to transport the printed paper after
fixing of one side toward REGI direction.
