MX-FN19  ADJUSTMENTS AND SETTINGS  3 – 1
MX-FN19
Service Manual
 
[3] ADJUSTMENTS AND SETTINGS
1. Basic adjustments
A. Upper curl mode
Paper may not be stacked properly depending on the paper state.
(Refer to the figure below.)
In such a case:
1) Turn back and set the paper in the paper feed cassette.
If the upper curl is greater than that before resetting the paper,
turn back the paper again to set in the previous state. 
2. Adjustments when replacing parts
A. Adjustment of alignment position
This adjustment is required when the finisher controller PCB is
replaced or when it is required to change the alignment position for
some reason.
1) Remove the rear cover in the finisher.
2) Check to confirm that the power of the host machine is turned
OFF, and set SW104 on the finisher controller PCB as shown
below, according to the paper used for the adjustment.
3) Turn ON the power of the host machine.
4) Press the SW103 on the finisher controller PCB once.
* When the SW103 is pressed, the swing guide is opened to
shift the alignment plates to the specified position.
5) Insert ten sheets of A4/LTR paper between the alignment
plates, and push the paper so that it is in contact with the stop-
per.
6) Press the SW101 or SW102 on the finisher controller PCB
until the alignment plates come in contact with paper.
* When the SW101 is pressed, the alignment plate is shifted
to the front side by 0.42mm.
* When the SW102 is pressed, the alignment plate is shifted
to the rear side by 0.42mm.
7) After the adjustment is completed, remove the paper, and
press the SW103 on the finisher controller PCB once to save
the adjustment value.
8) Set all the bits of the SW104 on the finisher controller PCB to
OFF.
9) Turn OFF the power of the host machine, and install the rear
cover of the finisher.
B. Adjustment of staple position
This adjustment is performed when the finisher controller PCB is
replaced or when it is required to change the staple position for
some reason. If the paper used for the adjustment is of AB series,
front/back stapling adjustments are performed for A4/A4R, respec-
tively. When the paper used for the adjustment is of inch series,
front/back binding adjustments are performed for LTR/LTRR,
respectively.
1)
Remove the rear cover of the finisher.
2)
Check to confirm that the power of the host machine is turned
OFF, and set the SW104 on the finisher controller PCB as
shown below, according to the paper used for the adjustment
and the stapling position.
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.
