CHAPTER 5 TROUBLESHOOTING
1.1.3 Adjusting the Stapling Position
(rear 1-point)
If you have replaced the EEPROM
(IC102) on the finisher controller PCB or
the stapler, make the following adjustments:
1) Using the door switch actuator, turn on
the two door switches. Set SW973 on
the SW973 as follows:
AB-configuration
ON
1 2 3 4 5 6 7 8
Inch-configuration
ON
1 2 3 4 5 6 7 8

2) Press SW976 on the switch PCB.
• The swing guide of the finisher opens
and, at the same time, the front aligning
plate and the rear aligning plate return
to home position. Then, the front align-
ing plate and the rear aligning plate
move to the rear 1-point stapling posi-
tion. The stapler also moves to the rear
1-point stapling position. The setting of
DSP971 on the switch PCB indicates
the latest setting, which is between '-12'
and '12'.
3) Keep several sheets of A4 or LTR paper
together, and insert the stack into the
holding tray. At this time, be sure to butt
the trailing edge of the stack again the
rear aligning plate.

• If the gap between the front aligning
plate and the paper front edge is 1 mm
or more, turn off the power, and shift all
bits of SW973 to OFF to stop the ad-
justment. Then, adjust the alignment
width, and then start over.
4) Press SW976 note switch PCB.
• The stapler executes stapling.
5) Take out the stack of sheets, and check
the stapling position against the stan-
dard. If the stapling position is correct,
end the adjustment. Turn off the power,
shift all bits of SW973 to OFF, and turn
on the power once again. If you need to
correct the stapling position, go to the
following step:
