MX-FNX2/AR-PN1/MX-RBX1 SELF DIAG MESSAGE AND TROUBLE CODE 9 – 5
Procedure
1
Check the delivery belt home position sensor (FOBHPD).
Is the sensor normal?
2
Is the wiring between the finisher controller PCB and the
stack delivery motor (FAM) normal?
3
Try turning the stack delivery motor (FAM) by hand.
Is the rotation smooth?
4
Try replacing the stack delivery motor (FAM).
Is the problem corrected?
Procedure
1
Check the paper surface sensor (FSLD).
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 lift
motor (FLM) as soon as the tray is driven?
4
Check the wiring from the finisher controller PCB to the lift
motor (FLM); is it normal?
Procedure
1
Is the tray as far as the lift upper limit sensor (FULD)?
2
Check the lift upper limit sensor (FULD). Is the sensor
normal?
3
Check the wiring from the finisher controller PCB to the lift
upper limit sensor (FULD); 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 lift motor lock sensor (FLE).
Is the sensor normal?
Procedure
1
Check the alignment home position sensor (front; FFJHPD).
Is the sensor normal?
2

alignment plate motor (front; FFJM) normal?
3
Is there mechanical trapping in the alignment plate path?
4
Try replacing the alignment motor (front; FFJM).
Is the problem corrected?
Procedure
1
Check the alignment home position sensor (rear; FRJHPD).
Is the sensor normal?
