3.1 Setting Perforating Block

) Loose Thumb Screw and squeeze Release

Levers by fingers to slide Perforating Block
right or left. Refer guide scale.

NOTE：

Before setting Perforating Block, make
sure to place Blade Position Reference at
center position so that fine adjustment
may be possible after the Block is
installed.
Refer “3.4.1 Adjusting line location”

(2) Fitting and fixing Blade Receipt Roller

- Loosen Roller Fixing Screw by Phillips Screw Driver and place Blade Receipt Roller fit
to the Perforating Blade.

- Then fix Roller Fixing Screw.

CAUTION：

While fixing Thumb Screw, press Thumb Screw towards Block Mounting Arm
so that Perforating Block sets square to Block Mounting Arm.
This helps the paper to be fed straight.

CAUTION：

Perforating Blade is designed always to be pressed against Blade Receipt Roller.
Do not move the Roller without squeezing Release Levers.
When Levers are squeezed, they give distance between Blade and Roller.

CAUTION：

Roller Fixing Screw must be fixed at the
position where Transport Shaft has flat cut.
Otherwise, the Blade Receipt Roller will
not be fixed to the Shaft and the Roller
may be damaged.

(3) Setting Paper Transport Rollers, Upper and Lower, at proper position
Place the Paper Transport Roller where they can grip paper positively.
Firstly, loosen Lower Philips Fixing Screws on both sides.

Slide and position them to the appropriate location and fix them.

Then, loosen Thumb Screws of Upper Transport Rollers on both sides.
Slide and position them so that Upper Transport Rollers ride on the Lower Transport
Rubber Rings.

CAUTION：

Press Thumb Screw to Block Mounting Arm when fixing the Perforating Block.
This helps the paper to be fed straightly.

CAUTION：

Depending location of perforating line, it may not always be possible to place
Upper Transport Roller riding on the two Rubber Rings.
In this case, we have to live with single Rubber Ring.
However, as much as possible, try to use two Rubber Rings at both sides for
stable paper feeding.

【Perforation Examples】

(1) Perforating at the center of a sheet

- Place Blade Position Reference to 0 (Zero) position of the scale.

Blade Position Reference

(2) Perforating two lines on a sheet by single perforation block.

- Place Blade Position Reference to adequate position and perforate.

- After first perforation done, reload the sheet to Paper Feed Tray reversing the paper
position.

- Then perforate 2nd line again.

1st Perforation 2nd Perforation

Further information：

If desired to perforate two lines by one operation, add one additional perforating block
(optional) to the transport shaft.
Note due to frame size of perforating block, perforating too closed lines or too far apart
lines may be limited.
Refer “ 4. Adding Perforation Unit “

NOTE：

Scale graduation and Blade Position Reference are for guidance only.
To perforate at the accurate position, use fine adjustment mechanism.
Refer “ 3.4.1 Adjusting line location ”

How to Replace the Separator with Thick-paper Separator

When fed, thicker paper might be damaged because of the friction between a paper feed
roller and a separator.
You should change the separator with Thick-paper Separator in that case.
