MX-FNX4  ADJUSTMENTS  8 – 2

3) Turn ON the power of the host machine.
4) Press the SW103 on the finisher controller PCB once.

* When SW103 is pressed, the swing guide is opened, and

the alignment plates are shifted to the specified positions.

5) Insert a sheet between the alignment plates, and push it so

that it is in contact with the stopper. Push the paper so that the
rear edge is in contact with the rear alignment plate.
* If there is a clearance of 1mm or more between the front

alignment plate and the front edge of paper, stop the adjust-
ment of staple position, and adjust the alignment position.
Then, perform adjustment of the staple position again.

6) Press the SW103 on the finisher controller PCB once to per-

form stapling. Since, however, paper is not discharged, the
stapled paper must be manually removed and the stapling
position must be checked.

7) Press the SW103 on the finisher controller PCB once.
8) If the stapling position is proper, insert a sheet of paper

between the alignment plates, and push it so that it is in con-
tact with the stopper. Push the paper so that the rear edge is in
contact with the rear alignment plate. Press the SW103 once
(stapling/adjustment value saving), and go to the step 11).

9) To adjust the stapling position, press the SW101 or SW102 on

the finisher controller PCB.
* When the SW101 is pressed, the stapling position is shifted

to the front side by 0.49mm.

* When the SW102 is pressed, the stapling position is shifted

to the rear side by 0.49mm.

10) Repeat the steps 5) and 6) to check that the stapling position is

properly adjusted.

11) Set all the bits of the SW104 on the finisher controller PCB to

OFF.

12) Turn OFF the power of the host machine, and install the rear

cover of the finisher.

To adjust the folding position, change the setting of bits from 6 to 8
of the DIPSW1 on the saddle stitcher controller PCB, and adjust
the folding position to the stitch position. (Adjust the paper position-
ing plate shift amount from the stitch position to the folding posi-
tion.)
If the saddle stitcher controller PCB is replaced, shift the setting of
the DIPSW1 on the old PCB to the new PCB. If the folding position
must be changed for some reason, this adjustment should be per-
formed.
1) Check to confirm that the power of the host machine is turned

OFF, and separate the finisher from the host machine. If the
optional punch module is installed, remove it from the finisher.

2) Remove the PCB cover, and set the bits from 1 to 4 of the

SW504 on the saddle stitcher controller PCB as shown below:

3) Remove the rear cover, and open the inlet cover of the saddle

stitcher. Then, fix the inlet cover sensor (FSINDD) and the inlet
door switch (FSINDSW) actuator with tape.

4)

Put a mark on the top of the paper before paper feeding. Use
two sheets of A3 or LDR paper.

5)

Turn ON the power of the host machine.

6)

Press the SW1 of the saddle stitcher controller PCB. (When
LDR is used, keep pressing for 3 sec or more.) Then, the feed
motor (FSFM) starts running.

7)

Feed two sheets of paper from the saddle inlet cover section.
Feed paper until the paper lead edge is in contact with the
paper positioning plate.

8)

Close the inlet cover.

9)

Press the SW1 of the saddle stitcher controller PCB.
* The saddle stitcher section stitches, folds, and discharges

paper automatically,

10) Measure the distance (L) between the stitch position and the

folding position. There are a "positive adjustment width" and a
"negative adjustment width" depending on the relations of the
stitch position and the folding position.
* If the stitch position is lower than the folding position, the

width is the "positive adjustment width."

* If the stitch position is higher than the folding position, the

width is the "negative adjustment width."

Do not change the

setting of bits from 5 to 8.
