Indicates a high degree of potential danger. Ignoring the warning may result in death or
serious injury of personnel.
CAUTION
Indicates a medium degree of potential danger. Ignoring the caution may result in injury of
personnel or damage to properties.
Examples of pictorial symbols
A circle with a line through it indicates a prohibited action. The particular act
prohibited is indicated by a picture inside the circle. ( In the example on the right
indicates ‘disassembly is prohibited.’
A black disc indicates an instruction , or sometimes a prohibited action. The
instruction itself is indicated by pictorial symbols drawn in white on the disc. ( In the

3. Paper flow and operating principle
3-1 Folding section
1 Papers loaded on the feed tray are separated to 1
sheet by the separator unit when being fed by the
paper feed ring.
(The timing for feeding the paper is controlled by the
PPS 1 which senses paper flow.)
2 In the double feed detecting section, the paper presses
up the upper double feed detection roller when it passes
between the rollers. When the upper roller is pressed
up higher than reference position, double feed is detected
and the machine stops.
(Error message ‘DOUBLE FEED’ will appear in the display.)
3 The paper passed through the double feed detection
section is fed to the folding tray 1 by the folding rollers
1 and 2, and stops at the stopper. The stopped paper
sags and is fed to the path between the folding rollers
2 and 3, and then is fed to the folding tray 2.

4 The paper fed to the folding tray 2 sags by bumping
the stopper as well as the flow in the folding tray 1,
and is fed to the path between the folding rollers 3
and 4, and then is fed to the sealer section by the
ejection roller.
(When V-fold is executed, the paper is fed directly
to the path between the folding rollers 3 and 4 from
the folding tray 1 by leading with the turn guide.)
3-2 Sealer section
1. The paper fed to the sealer section touches the stopper,
and is fed to the pressure roller section by the feed
rollers and roller.
2. The temporary sealed part in the folding section of the
paper fed is peeled off by the bracket F (upper and lower)
installed adjacent to the feed roller, and then is fed to the
pressure roller section.
3. The paper is applied by strong pressure between the
pressure rollers, and pressure sensitive adhesive
parts are adhered.

[Adjustments]
Adjusting double feed detection unit
Parts names
1. Turn the eccentric pin until the gap between the upper
and lower detection rollers is at the maximum setting.
Insert a sheet of 70kg (approximately) paper between
the detectio rollers.
2. Turn the eccentric pin until it touches the hole,
Then fasten it with the screw.
3. Adjustment completes when the lever does not move
by running a sheet of paper between the detection
rollers and it moves by running 2 sheets of paper.

Adjusting folding roller
1. Loosen the 2 screws holding the bearing holder of each roller.
Slide the folding rollers 1 and 3 along the elongate hole taking
the roller 2 as reference so that these rollers are pressed up the
roller 2.
2. Adjust the folding roller 4 taking the folding roller 3 adjusted in
the step 1 as reference.
* Each roller should be symmetrical to the left and right, and
there should be no gap between rollers. (Asymmetrical roller
pressure causes snaking or wrinkling.)
* After adjustment, a roller should rotate without flat belt and all rollers should drive together.
Adjusting pressure of pressure roller
1. Turn the screw shaft for adjusting pressure
until the top edge of the shaft touches the
pin top.
2. Turn the screw shaft clockwise with a handle
for 180 from the contact position in the step 1.
(symmetrical to the left and right)
* Turning the screw shaft clockwise increases
the pressure.
* Turning the screw shaft counterclockwise
decreases the pressure.
Note: Asymmetrical roller pressure causes snaking or uneven
pressurizing.
