(rear; RJHPS)
Wiring
Aligning plate (rear)
Alignment motor (rear; FRJM),
Finisher controller PCB
Procedure
1
Check the paper surface sensor. Is the sensor normal?
2
Check the tray up/down mechanism. Is the mechanism normal?
3
Is 24 VDC supplied from the finisher controller PCB to the shift
motor as soon as the tray is driven?
4
Is the wiring between the finisher controller PCB and the shift
motor normal?
Procedure
1
Is the tray as far as the shift upper limit sensor?
2
Check the shift upper limit sensor. Is the sensor normal?
3
Check the wiring from the finisher controller PCB to the shift
upper limit sensor; is it normal?
Procedure
1
Is the tray in UP position?
2
Is power supplied to the finisher controller PCB as soon as the
tray is driven?
3
Is there a fault in the tray up/down mechanism?
4
Check the shift motor clock sensor.
Procedure
1
Check the aligning plate home position sensor (front).
Is the sensor normal?
2
Is the wiring between the finisher controller PCB and the front
alignment plate motor (front) normal?
3
Is there mechanical trapping in the aligning plate path?
4
Try replacing the Alignment motor (front).
Is the problem corrected?
