CHAPTER 5 TROUBLESHOOTING
5 Self Diagnosis
5.1 Outline
The CPU on the machine’s finisher controller PCB is equipped with a mechanism to check
the machine condition as needed; when it detects a fault, the machine communicates the fact to
the host machine in the form of a code and a detail code.
The host machine indicates the code on its control panel. (The detail code may be checked in
the host machine’s service mode.)

Timing of detection
• The communication between the host machine
and the finisher is interrupted. This error is de-
tected by the host machine.
• The checksum for the finisher controller PCB has
an error when the power is turned on.
• The stack feed roller (upper) does not leave the
stack feed roller (upper) home position sensor
when the feed motor has been driven for 2 sec.
• The stack feed roller (upper) does not return to
the stack feed roller (upper) home position sensor
when the feed motor has been driven for 2 sec.
• The delivery belt does not leave the delivery belt
home position sensor when the stack delivery
motor has been driven for 3 sec.
• The delivery belt does not return to the delivery
belt home position sensor when the stack deliv-
ery motor has been driven for 3 sec.
• The aligning plate (rear) does not leave the align-
ing plate home position sensor (rear) when the
alignment motor has been driven for 3 sec.
• The aligning plate (rear) does not return to the
aligning plate home position sensor (rear) when
the alignment motor (rear) has been driven for 3
sec.
