CONTENT
[Phenomenon]
Paper may exit without being stapled though in the staple mode.
[Cause]
After the sheet is stapled on the stapling tray in the staple mode (the front and back of the stacked
sheets are aligned at the alignment plate on the rear side of the staple tray), stapling is performed and
the stacked sheets exit. If the alignment plate is over-aligned, the sheet becomes warped (the rising of
the center area), and the paper detection sensor on the staple tray goes OFF. It is then judged that t
here is no paper, and so stapling is not operated.

If the above occurs, carry out A-2 "Adjusting the Alignment Position" listed the following file, to adjust
the aligning quantity of the alignment plate suitably.
The sending file is the same as the file for BSI "F99E618". The shaded points were shown for the

CHAPTER 6 TROUBLESHOOTING
1. Adjusting the Height Sensor (PS1)
Perform the following adjustments whenever you have replaced the finisher controller
PCB or the height sensor (PS1).
1) Set SW3 on the finisher controller as indi-
cated.
Figure 6-101
2) Put blank plain paper (A4 or LT) on all
trays.
3) Press SW2 on the finisher controller PCB.
A press causes the finisher to execute au-
tomatic adjustment, in which the tray unit
will shift tray 1 and then tray 2 in sequence.
• At the end of adjustment, trays will return
to home position.
• During adjustment, LED 1 flashes. At the
end of adjustment, LED1 turns and remains on.
• If automatic adjustment fails, the mechanism stops while the tray in question is
being adjusted. (At the same time, LED1
turns off.)
4) Shift all bits on SW3 to OFF*, and turn
off the copier once.
Figure 6-102
3) If you are using A4 paper, press SW2 on
the finisher controller PCB. If you are using L T paper , on the other hand, press SW1
on the finisher controller PCB.
• A press on SW2/1 will open the swing
guide and cause the alignment plate to
move to A4/LT position.
4) Place 10 sheets of A4/LT paper between
the alignment plate and the guide plate,
butting them against the stoppers.
5) Press SW2 or SW1 on the finisher controller PCB, and butt the alignment plate
against the sheets.
• A press on SW2 will shift the alignment
plate to the front in increments of 0.35 mm.
• A press on SW1 will shift the alignment
plate to the rear in increments of 0.35 mm.
2. Adjusting the Alignment Position
If you have replaced the finisher controller PCB or if an alignment fault occurs, make
the adjustments that follow. Performing the
steps will affect all paper sizes.
1) Remove the rear cov er of the finisher unit.
2) Set SW3 of the finisher controller PCB as
indicated.
