Adjusting the Staple Position

Adjust as follows if you have replaced the
finisher controller PCB. Performing the follow-
ing procedure affects all paper sizes and all sta-
pling positions.
1) Set DIP_SW (SW3) on the finisher con-
troller PCB as follows.

2) If you are using A4 paper for the adjust-
ment, press SW1 on the finisher controller
PCB. If you are using LT paper for the ad-
justment, press SW2 on the finisher con-
troller PCB.
Pressing SW1 (SW2) opens the swing
guide and causes the knurled belt to rotate.
3) Within five seconds after pressing the
switch, place two sheets of A4 (LT) paper
between the alignment guide and the guide
plate, butting them against the stoppers.

• When the finisher detects the paper, it low-
ers the swing guide and performs stapling
(rear, 1-position). Note, however, that
manually stapled paper should be taken out
as delivery is not performed.
4) If the stapling position is correct, set all
bits of the DIP_SW to OFF to end the ad-
justments.
If you need to change the stapling posi-
tion, adjust by performing the following
procedure.
5) To match the position of the staple on the
paper, press SW1 or SW2 on the finisher
controller PCB for the necessary number
of times.
• Each press of SW1 shifts the stapling po-
sition towards the front in 0.3 mm incre-
ments.
• Each press of SW2 shifts the stapling po-
sition towards the rear in 0.3 mm incre-
ments.
6) Press SW1 and SW2 simultaneously.
• This opens the swing guide, and causes the
knurled belt to rotate. Placement of two
sheets of A4 (LT) paper causes the finisher
to start stapling.
7) Check the stapling position. If good, set
all bits of the DIP_SW to OFF. If readjust-
ments are necessary, repeat the adjustment
from step 5).
Note
The settings held by the finisher controller
PCB are changed as soon as SW1 or SW2 is
pressed. As such, to recover the previous
settings after pressing these switches, you
must press the other of the two switches as
many times as you pressed previously.
