Rear alignment error (Finisher-Q3/
Q4)
The home position sensor does not
go off within 1000 msec after the
start of operation when the rear
aligning plate is moved form home
position.
Replace the finisher controller PCB. Replace the
rear alignment motor. Check the rear aligning
plate drive mechanism. Check the rear alignment
home position sensor.

Front alignment error (Finisher-S1)
The home position sensor does not
go on within 2.0 sec when the front
aligning plate is moved to home
position.
Replace the finisher controller PCB. Replace the
front alignment motor. Check the front aligning
plate drive mechanism. Check the front alignment
home position sensor.
E537-
8002
Front alignment error (Finisher-S1)
The home position sensor dos not go
off within 1.0 sec when the front
aligning plate is shifted from home
position.
Replace the finisher controller PCB. Replace the
front alignment motor. Check the front aligning
plate drive mechanism. Check the front alignment
home position sensor.
