Service Manual

 

Each adjustment item in the adjustment item list is identified with its
own JOB No. The adjustments are basically executed in the
sequence from a smaller JOB No. to a larger JOB No.
There is, however, no need to perform all the adjustment items.
Only the necessary items may be executed depending on the situa-
tion.
Unnecessary items may be skipped to go to the next necessary
item. In this case, of course, the adjustment sequence could be
executed from a smaller to a larger JOB No.
If the above is neglected, the adjustment cannot be completed nor-
mally, resulting in a trouble.
Start of simulation
1)

Press [COPY MODE] key to enter the copy mode.

2)

Press [P] (Program) key 

→ [*] (Asterisk) key → [C] (Clear) key

→ [*] (Asterisk) key in this sequence.

3)

The display is shifted to the simulation main number entry
screen (entry standby screen).

 

1)

When the punch PWB is replaced, the destination setting must
be performed.

2)

For destination setting, the DIP switch (SW1) on the punch
PWB is used.

3)

The relationship between the switches and the destinations is
shown in the table below.

 

When the flapper solenoid is disassembled, an adjustment is
required when assembling.
1)

Loosen the solenoid fixing screw.

2)

Slide the solenoid in the direction of arrow A.

3)

Hold the solenoid, and pull out the plunger in the direction of
arrow B.

4)

Gradually slide the solenoid in the direction arrow C without
touching the plunger, and fix it to the position where the gap
between lever X and Y is 0 - 0.5mm.

5)

Manually turn ON the solenoid, and check to confirm that the
gate tip is over the lower surface of the paper guide.
