I. ADJUSTMENTS

A. Electrical System (finisher

unit)

CHAPTER 6 TROUBLESHOO TING

1. Adjusting the Height Sensor (PS1)

Perform the following adjustments when­ever you have replaced the finisher controller
PCB or the height sensor (PS1).

1) Set SW3 on the finisher controller as indi-

cated.

Figure 6-101

2) Put blank plain paper (A4 or LT) on all

trays.

3) Press SW2 on the finisher controller PCB.

A press causes the finisher to execute au-

tomatic adjustment, in which the tray unit

will shift tray 1 and then tray 2 in sequence.

• At the end of adjustment, trays will return
to home position.

• During adjustment, LED 1 flashes. At the
end of adjustment, LED1 turns and re­mains on.

• If automatic adjustment fails, the mecha­nism stops while the tray in question is
being adjusted. (At the same time, LED1
turns off.)

4) Shift all bits on SW3 to OFF*, and turn
off the copier once.

Figure 6-102

3) If you are using A4 paper, press SW2 on
the finisher controller PCB. If you are us­ing L T paper , on the other hand, press SW1
on the finisher controller PCB.

• A press on SW2/1 will open the swing
guide and cause the alignment plate to
move to A4/LT position.

4) Place 10 sheets of A4/LT paper between
the alignment plate and the guide plate,
butting them against the stoppers.

5) Press SW2 or SW1 on the finisher control­ler PCB, and butt the alignment plate
against the sheets.

• A press on SW2 will shift the alignment
plate to the front in increments of 0.35 mm.

• A press on SW1 will shift the alignment
plate to the rear in increments of 0.35 mm.

2. Adjusting the Alignment Position

If you have replaced the finisher control­ler PCB or if an alignment fault occurs, make
the adjustments that follow. Performing the
steps will affect all paper sizes.

1) Remove the rear cov er of the finisher unit.

2) Set SW3 of the finisher controller PCB as

indicated.

CHAPTER 6 TROUBLESHOOTING

6) Press SW2 and SW1 simultaneously to
store the adjustment value. (This will lo wer
the swinging guide.)

7) Shift all bits of SW3 to OFF*, and install
the rear cover of the finisher unit.

3. Adjusting the Stapling Position

(stapler movement range)

Make the adjustments that follow if you

have replaced the finisher controller. Perform­ing the steps will affect all paper sizes and all
stapling positions.

1) Remove the rear cover from the finisher
unit.

2) Set SW3 on the finisher controller PCB as
indicated.

Figure 6-104

3) If you are using A4 paper, press SW2 on
the finisher controller PCB. If you are us­ing LT paper, press SW1 on the finisher
controller PCB.

• A press on SW2/1 will open the swing
guide and cause the feed belt to rotate.

4) Within 5 sec after pressing the switch, place
two sheets of A4/LT paper between the
alignment plate and the guide plate, butt­ing it against the stoppers.

• When the finisher detects the paper , it will
lower the swing guide and execute stapling
(rear, 1-point). Take out the stapled paper
manually , howe ver; deliv ery operation will
not be executed.

Figure 6-105

5) If the stapling position is correct, shift all
bits on SW3 to OFF* to end the adjust­ments. If you need to change the stapling
position, on the other hand, go to the next
step.

6) To suit the position of the staple on the
paper, press SW2 or SW1 on the finisher
controller PCB as many times as necessary .

• A press on SW2 will shift the stapling po­sition to the front in increments of 0.3 mm.

• A press on SW1 will shift the stapling po­sition to the rear in increments of 0.3 mm.

6-2

Figure 6-106

7) Press SW2 and SW1 simultaneously.

• The press will open the swing guide, and
cause the feed belt to rotate. Placement of
two sheets of A4/LT paper will cause the
finisher to start stapling operation.

8) Check the stapling position. If good, shift
all bits of SW3 to OFF*. If readjustments
are necessary, go back to step 6).

CHAPTER 6 TROUBLESHOO TING

Tray shift time

Within a specific period of time:

LED 1 lights (normal).
When more than a specific period of
time:

LED 1 goes out (abnormal).

3) Likewise, when SW1 is pressed, the tray
is lowered by one step. Note, ho wever , that
tray movement is canceled when the cur­rent position is the lowest.

5. Delivery feeding speed check

Make sure that the delivery feeding speed

is 650 mm/sec or more with the delivery feed­ing motor fully ON.

Make sure that the deliv ery feeding motor

can perform its required functions at all times.

1) Set the DIP switch settings on the Finisher
controller board as follows:

Note:

The settings held by the finisher controller
are changed as soon as SW2 or SW1 is
pressed. As such, to recover the previous
settings after the press, you must press the
other of the two switches as many times as
you pressed previously.

4. Tray shift time check

Make sure that the tray shift time is within
a specific period of time (under a load of 1500
sheets of A4 size paper of equivalent).

1) Set the DIP switch settings on the Finisher

controller board as follows:

Figure 6-107

Figure 6-108

2) When SW2 is pressed, the delivery feed­ing motor operates, the number of pulses
from the encoder fed by the delivery feed
motor is calculated, and LED 1 lights or
goes out according to the following condi­tions:

Delivery feeding speed

When 650 mm/sec or less:

LED 1 lights (normal).

When less than 650 mm/sec:

LED 1 goes out (abnormal).

3) When SW1 is pressed, checking of the abil­ity of the delivery feeding motor to per­form its functions is carried out.

4) Stop the delivery feeding motor by press­ing the SW2.

2) When SW2 is pressed, the time required
for tray shifting is calculated, and LED 1
lights or goes out according to the follow­ing conditions. Note, however, that tray
movement is canceled when the current
position is the 2nd bin.

B. Electrical System (saddle

stitcher unit)

1. Adjusting the Folding Position

The folding position is adjusted by chang­ing the settings of bits 6 through 8 of DIPSW1
on the saddle stitcher controller PCB so as to
match with the stitching position (i.e., adjust­ing the distance over which the paper position­ing plate is moved to the folding position from
the stitching position).

If you have replaced the saddle stitcher
controller PCB, be sure to set the new DIPSW1
so the settings will be the same as those on the
old DIPSW1. If, for any reason, you must
change the folding position, perform the fol­lowing steps:

CHAPTER 6 TROUBLESHOO TING

1) Remove the PCB cover, and set bits 1
through 4 of DIPSW1 on the saddle stitcher
controller PCB as indicated.

Figure 6-113

2) Remove the rear cover of the saddle stitcher
unit, and tape the actuator of the inlet cover
open sensor (PI9S) and the inlet cover open
detecting switch (MS1S) of the saddle
stitcher unit in place.

3) Press SW2 on the saddle stitcher control­ler PCB so that the feed motor (M1S) starts
to rotate.

• If SW2 is pressed for 1 second or less, the
adjustment mode will be for A3 size.

• If SW2 is pressed for 3 seconds or more,
the adjustment mode will be for LD size.

4) Before slot in the paper, put a marking at
the top of the paper . (Y ou will be using tw o
sheets of A3 or LD paper.)

5) Open the inlet cover , and slot in two sheets
of paper. (Push them in by hand until the
leading edge of the sheets butts against the
paper positioning plate.)

Figure 6-115

6) Close the inlet door.

7) Press SW2 on the saddle stitcher control­ler PCB.

• The saddle stitcher unit will “stitch” the
sheets, and fold and deliver the stack auto­matically .

8) Measure the distance (L) between the
stitching position and the folding position.
Then, perform “positive width adjustment”
or “negative width adjustment” to suit the
relationship between the stitching position
and the folding position.

• If the stitching position is below the fold­ing position, perform “positive width ad­justment.”

• If the stitching position is above the fold­ing position, perform “negative width ad­justment.”

Figure 6-114

6-5

CHAPTER 6 TROUBLESHOOTING

• If for “negative width adjustment,”
set DIPSW1 so that the sum resulting from
addition of the interval to the appropriate
setting is provided.
For instance, if DIPSW1 is currently set to

-1 and the interval is -0.75 mm, set
DIPSW1 to reflect +2.

Figure 6-116

9) By referring to Table 6-101 below, change
the settings of bits 6 through 8 on DIPSW1.

• If the width adjustment is ‘0’,
the stitching position and the folding posi­tion match, requiring no change.

• If for “positive width adjustment,”
Set DIPSW1 so that the difference result­ing from subtraction of the interval from
the appropriate setting in Table 6-101 is
provided.
For instance, if the DIPSW1 is currently
set to +2 and the interval is +1 mm, set
DIPSW1 to reflect -2.

Table 6-101

10) Shift bits 1 through 4 on DIPSW1 to OFF .
