MX-FNX2/AR-PN1/MX-RBX1  ADJUSTMENTS  8 – 1

âºíuÇ´

Service Manual

 

The folding position is adjusted by matching it with the stapling
position.
If you have replaced the finisher controller PCB, you must transfer
the existing settings to the new PCB. Perform the following if the
folding position must be adjusted for some reason.

NOTE: Both the folding and stapling positions may deviate for

some type of paper. In such a case, change the "middle
stapling position" in the user mode of the host machine.

1)

Set SW1 on the finisher controller PCB as follows:

2)

Adjust the folding position by pressing the PSW1 or PSW2 on
the finisher controller PCB a required number of times. Press-
ing 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.

3)

When adjustment of the folding position is complete, set all bits
of the SW1 on the finisher controller PCB to OFF.

4)

Enter the bind mode of the host machine and check whether
the folding position is adjusted properly. If adjusted improperly,
adjust the folding position again.

The stapling position is adjusted by matching it with the folding
position.
●

 This adjustment is necessary:

• If you have replaced the finisher controller PCB.
• If the stapling position must be adjusted for some reason.

NOTE: Both the folding and stapling positions may deviate for

some type of paper. In such a case, change the "middle
stapling position" in the user mode of the host machine.

1)

Set SW1 on the finisher controller PCB as follows:

2)

Adjust the stapling position by pressing the PSW1 or PSW2 on
the finisher controller PCB a required number of times. Press-
ing the switch once moves the stapling position about 0.14
mm.
• To move the stapling position in the "-" direction, press the

PSW1.

• To move the stapling position in the "+" direction, press the

PSW2.

• Pressing the PSW1 and PSW2 at the same time clears the

adjustment value.

3)

When adjustment of the stapling position is complete, set all
bits of the SW1 on the finisher controller PCB to OFF.

4)

Enter the bind mode of the host machine and check whether
the stapling position is adjusted properly. If adjusted improp-
erly, adjust the stapling position again.

This mode is used to increase the accuracy of paper alignment in
the simple load offset mode by discharging paper one by one to the
offset tray.
1)

Set the SW1 of the finisher control PWB as shown below.

2)

Turn on the power.

This adjustment is available only in the diagnostic mode (Sim 3-10)
of the host machine. The range of punch hole displacement is
between 3 and -3 in 1-mm increments. A higher setting will move
the punch hole toward the leading edge of sheet.

Perform the following when the punch controller PCB, horizontal
registration sensor (photosensor PCB/LED PCB), or waste full sen-
sor (waste full photosensor PCB/waste full LED PCB) has been
replaced.
1)

Shift bits 1 through 4 on the punch controller PCB as follows:

2)

Press SW1002 or SW1003 on the punch controller PCB. A
press will automatically adjust the sensor output.
• The adjustment is over when all LEDs on the punch control-

ler PCB are ON: LED1001, LED1002, LED1003.

3)

Shift all bits of DIPSW1001 to OFF.

MX-FNX2/AR-PN1/MX-RBX1  ADJUSTMENTS  8 – 2

Perform the following to register the type of punch unit (number of
holes) used to the IC on the punch controller PCB for identification
by the finisher. Be sure to register the type whenever you have
replaced the punch controller PCB.
1)

Set bits 1 through 4 on the DIPSW1001 on the punch control-
ler PCB as follows:

2)

Press SW1002 on the punch controller PCB to select the
appropriate number of punch holes.
• Each press on SW1002 moves the selection through the fol-

lowing (repeatedly from top to bottom).

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 indication 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.

1)

Turn off the host machine.

2)

Set bits 1 through 4 on the punch controller PCB as follows:

3)

Press SW1002 and SW1003 on the punch controller PCB at
the same time.
• The presses will initialize the EEP-ROM. At the end, all

LEDs (LED1001, LED1002, LED1003) will go ON.

4)

Adjust the sensor output, and store the number of punch
holes. Adjust the punch hole position adjustment (horizontal
registration) of necessary.

1)

Select "FINISHER ADJUSTMENT" in SIM 3-10.

2)

Select a setup item and change the setup value.

Adjustable setup range is as follows.
