MX-FNX2/AR-PN1/MX-RBX1 SELF DIAG MESSAGE AND TROUBLE CODE 9 – 7
Procedure
1 Check the punch home position sensor (FPHPD).
Is the sensor normal?
2 Check the punch motor lock sensor (FPMCK). Is the sensor
normal?
3 Is the wiring between the finisher controller PCB and the
sensor normal?
4 Is there a fault in the punch mechanism?
5 Try replacing the punch controller PCB. Is the problem
corrected?
Procedure
1 Check the horizontal registration sensor. Is the sensor
normal?
