3.13 Adjustment of the Finisher (MJ-1025) 
3.13.1 Adjusting the folding position (Electrical sy stem (Finisher/Saddle 
unit))
The folding position is adjusted by matching it wit h the stapling position.
If you have replaced the finisher controller PCB, y ou must transfer the existing settings to the new PC B. 
Perform the following if the folding position must  be adjusted for some reason.
Note: Note: 
Both the folding and stapling positions may deviate  for some type of paper.
In such a case, change the “middle stapling positio n” in the user mode of the host machine.
 (1) Set SW1 on the finisher controller PCB as follow s:
 Fig.3-128
(2) Adjust the folding position by pressing the PSW1  or PSW2 on the finisher controller PCB a 
required number of times. Pressing the switch once  moves the folding position about 0.16 mm.
 To move the folding position in the “-” direction,  press the PSW1.
 To move the folding position in the “+” direction,  press the PSW2.
 Pressing the PSW1 and PSW2 at the same time clears  the adjustment value.
 Fig.3-129
(3) When adjustment of the folding position is complete, set all bits of the SW1 on the finisher con-
troller PCB to OFF.
(4) Enter the bind mode of the host machine and chec k whether the folding position is adjusted prop-
erly. If adjusted improperly, adjust the folding po sition again.

3.13.2 Adjusting the sensor output (Electrical syste
m (Puncher unit; 
option))
Perform the following when the punch controller PCB , horizontal registration sensor (photosensor PCB/
LED PCB), or waste full sensor (waste full photosen sor PCB/waste full LED PCB) has been replaced.
 (1) Shift bits 1 through 4 on the punch controller P CB as follows:
 Fig.3-130
(2) Press SW1002 or SW1003 on the punch controller P CB. A press will automatically adjust the 
sensor output. 
 The adjustment is over when all LEDs on the punch  controller PCB are ON: LED 1001, 
LED1002, LED1003.
(3) Shift all bits of DIPSW1001 to OFF.

3.13.3 Registering the number of punch hole (Electri cal system 
(Puncher unit; option))
Perform the following to register the type of punch er unit (number of holes) used to the IC on the pun ch 
controller PCB for identification by the finisher.  Be sure to register the type whenever you have replac ed 
the punch controller PCB. 
.
(1) Set bits of 1 through 4 on the DIPSW1001 on the  punch controller PCB as follows:
 Fig.3-131
(2) Press SW1002 on the punch controller PCB to sele ct the appropriate number of punch holes.
 Each press on SW1002 moves the selection through t he following (repeatedly from top to bot-
tom).
(3) Press SW1003 on the punch controller PCB twice.  The presses will store the selected number of 
punch holes on the punch controller PCB. 
 A single press on SW1003 will cause the LED indica tion to flash; another press on SW1003 
will cause the indication to remain ON to indicate  the end of registration.
(4) Shift all bits of DIPSW1001 to OFF.

3.13.4 After replacing the EEP-ROM (IC1002) (Electri
cal system 
(Puncher unit; option))

(1) Turn off the host machine. 
(2) Set bits 1 through 4 on the punch controller PCB  as follows:
 Fig.3-132
(3) Press SW1002 and SW1003 on the punch controller  PCB at the same time.
 The presses will initialize the EEP-ROM. At the en d, all LEDs (LED1001, LED1002, 
LED1003) will go ON.
(4) Adjust the sensor output, and store the number o f punch holes.

3.14 Key Copy Counter (MU-8, MU-10)
To make a key copy counter available, the following  2 components must be installed to the equipment.
 Fig.3-133

(1) Remove the rear cover. 
(2) Remove the right upper cover-3, and cut  open the window for the key copy counter.
 Fig.3-134
(3) Pull out the harness connector from the hole 
of the machine frame, and cut the short har- 
ness of the connector. (Treat the cut harness 
properly to avoid it causing a short circuit  
with the machine frame.) Then, disconnect  
the dummy connector.

3.15 Adjustment of Dogleg
Dogleg is the name given to an image which is defor med approx. 48 mm of the trailing edge of the out-
put paper. 
Since adjustment has usually been performed when th e equipment was manufactured, dogleg image 
should not occur. However, if the following dogleg  image A or B does happen to occur, the following 
adjustment must be performed. An original with a li ne parallel to the feeding direction is used for the 
adjustment.
