5) If the stapling position is correct, set all bits

on SW3 to OFF to end the adjustments. If
you need to change the stapling position,
on the other hand, go to the next step.

6) To suit the position of the staple on the pa-

per, press SW1 or SW2 on the finisher con-
troller PCB as many times as necessary.

• Pressing SW1 will shift the stapling posi-

tion to the front in 0.3 mm increments.

• Pressing SW2 will shift the stapling posi-

tion to the rear in 0.3 mm increments.

7) Press SW1 and SW2 simultaneously.

• This will open the swing guide, and cause

the feed belt to rotate. Placement of one sheet
of A4/LT paper will cause the finisher to
start stapling.

8) Check the stapling position. If good, set all

bits of SW3 to OFF. If re-adjustments are
necessary, go back to Step 6.

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 the press, you must press the
other of the two switches as many times
as you pressed previously.

Perform this adjustment in the following

instances:

a.

When the finisher controller PCB or the
EEPROM (Q2) on the finisher controller
PCB has been replaced

b.

When something causes the winding
amount to fluctuate
The "winding amount" is the amount of dif-
ference between the First and Second sheets
wound onto the buffer roller device in the
feed direction.

2) Turn the host machine OFF then back ON

again.

3) Set the mode setting on the host machine to

"1" and the number of originals (A4 or LT)
to "3" in the staple mode.

4) Press the copy start key.

• Copying starts, three sheets for the first copy

are output as a stack on the staple tray, and
copying stops with the copies held at the
delivery roller.

5) Remove the stack of sheets from the fin-

isher delivery taking care to prevent the off-
set of the output sheets from changing.
