This adjustment must be performed when replacing the following
parts:

•

Sorter controller PWB

•

Bin paper sensor (S1, S2)

Note: To perform this adjustment, the bin unit must be assembled

completely in advance. If the adjustment is performed without
assembling the cover, etc., the sensor will receive external
lights, resulting in an error in adjustment.

1) Remove all the paper in the bins.

2) Remove the right cover, and set the DIP switch on the sorter

controller PWB as shown below.

∗

Do not move No. 6, which is used only for selection of the com-
munication system with the copier.

3) Press the manual staple key on the operation section of the

machine.

4) Check the status of the manual staple key on the operation sec-

tion of the machine.

ON:

Adjustment completed.

Blinking: Adjustment error

In case of an adjustment error, the error code of F1-91 is dis-
played on the copier.

5) When the manual staple key blinks, turn off and on the copier

power switch, check the status of the bin paper sensor (on the
light emitting side and the light receiving side) corresponding to
the error code, and perform the adjustment from procedure 1)
again.

6) After completion of the adjustment, return the DIP switch on the

sorter controller PWB to the original state.

This adjustment is performed when the following parts are replaced.

•

Sorter controller PWB

•

Guide bar home position sensor (PI3)

•

Guide bar oscillation motor (M3)

1) Prepare one sheet of A4 or letter paper for copying.

2) Remove all the paper from the bins.

3) Remove the right cover, and set the DIP switch (SW1) on the

sorter controller PWB as shown below. (Note that the setup con-
tent differs depending on the copy paper size.)

4) Place A4 or letter copy paper in the bin as shown below.

5) Operate the bin shift key (SW2, SW3) on the sorter controller

PWB to bring the guide bar into a slight contact with the copy
paper.

UP key (SW3):

Moves the guide bar to the paper.

DOWN key (SW2): Moves the guide bar apart from the copy

paper.

6) Under the state of procedure 4), press the manual staple key on

the operation section of the machine. The guide bar returns to the
home position and the adjustment value is stored.

1) Remove all the paper from the bins. Remove the right cover.

2) Set the DIP switch (SW1) on the sorter controller PWB as shown

below.

3) Place 5 sheets of A4 or letter paper in the first bin as shown

below.

4) Press the push switch (SW3) on the sorter controller PWB to shift

the stapler oscillation unit to the stapling position.

5) Press the push switch (SW2) on the sorter controller PWB and

press the manual staple key to staple and check the stapling
position.

6) If the stapling position is outside the specified range, adjust the

stapling position with the push switch (SW3).
Press the staple key of the sorter. The stapler oscillation unit
returns to the home position and the adjustment value is stored.

7) Return the DIP switch (SW1) to the original state and install the

right cover.

Process

Bin, bin roller

1) Bin roller height adjustment
2) Guide bar parallelism
adjustment

The dummy roller lower is of eccentric shape so that you can adjust
the height of the bin roller this is so you can adjust the height at which
the bin roller and  the lead cam tip touch.
When the bin roller is replaced or reassembled, check the standard
dimensions and change and adjust the installing angle of the dummy
roller lower if necessary.

1) Adjustment procedure

Stand up the bin unit straight. Measure the distance between the
upper dummy roller (1) and the bin roller (2). If the distance is too
large, rotate the lower dummy roller (3) counterclockwise. If the
distance is too small, turn it clockwise. Turn and adjust so that the
distance is about 97.8mm.

When the bin unit is disassembled or the top screw of the guide bar is
removed, adjust the guide bar parallelism.

1) Adjustment procedure

Set B5 paper or A4R paper in the 1st bin and in the 20th bin.
Push the guide bar (1) manually in the alignment direction to press
it onto the paper.
Check contact conditions of the guide bar and the paper in the 1st
bin and the 20th bin. If they are not parallel, loosen the screw (3)
of the guide bar holder (2).
