or physical damage.

this mark could result in the possibility of injury

Power Supply

This unit shall be installed near the socket-outlet where the plug on the power supply cord is

easily accessible.

Make sure the power supply used is always within the following range.

Power supply : 100 to 240 V AC, 50/60 Hz

When you power other appliances from the same AC outlet, make sure that the combined

power consumption does not exceed the power supply capacity.

Rated current (Rated power) : 2 to 1 A (140 W)

WARNING

Use only the power supply voltage speciﬁed on the main nameplate.

Using other voltages could result in a ﬁre or an electrical shock.

Make sure that the combined power consumption of the appliances to be connected does not exceed the capacity rating of the power outlets or plug receptacles.

Exceeding the capacity rating could cause the power outlets, plug receptacles, or power extension cords to overheat and catch a ﬁre.

SAFETY PRECAUTIONS

Operating Environment

Operate this unit in the following environment.

where the temperature range is between 5 and 35°C (–10 to +50°C in storage) where the humidity range is between 20 and 80% RH (10 to 90% RH in storage, however

no condensation) which is not subject to direct sunlight which is reasonably free from dust which is subject to little or no vibration which is free from air-borne salt where there are no harmful chemicals where the unit is not exposed to water

WARNING

Keep this unit and the power cord away from heaters and heater vents.

Excessive heat could melt the cover or power cord covering, and result in a ﬁre or an electrical shock.

Do not place metal objects or vessels containing liquids on top of the unit.

The entry of any metal object or liquid could result in a ﬁre or an electrical shock.

Do not insert any metal or easily-combustible object inside this unit.

This could result in a ﬁre or an electrical shock.

Do not use ﬂammable sprays inside or near the unit (e.g. when cleaning the unit).

Such ﬂammable gas may ignite and cause a ﬁre or combustion.

CAUTION

Do not install this unit in a location where there is excessive humidity or where contact with water is possible.

Poor choice of location could result in deterioration of the insulation, a ﬁre or an electrical shock.

Install this unit on a level, stable stand or ﬂoor, with sufﬁcient space around it.

Failure to do so could result in the unit overturning and causing injury.

Disconnect the power plug from the power outlet before attempting to move this unit.

Failure to do so could result in power cord damage, a ﬁre or an electrical shock.

Always disconnect the power plug from the power outlet when the unit is not to be used for an extended period.

Failure to do so could result in a ﬁre due to leakage current if the insulation should deteriorate.

iii

SAFETY PRECAUTIONS

Maintenance, etc.

Do not damage the power cord or power plug.

Do not scratch, alter, bend, twist, pull or place heavy objects on the power cord or power plug. This could result in damage, a ﬁre or an electrical shock.

Do not handle the power plug with wet hands.

This could result in an electrical shock.

Do not touch the power switch with wet hands.

Otherwise electric hazards may occur.

Do not remove the cover or back panel.

This unit contains high-voltage components that could cause an electrical shock.

WARNING

Do not disassemble, modify or repair this unit.

There is a danger of ﬁre, electrical shock or injury. Contact your dealer when repairs are necessary.

If any foreign object such as metal or liquid should enter this unit, immediately turn the unit off at the power switch and disconnect the power plug from the power outlet.

Failure to do so could result in a ﬁre or an electrical shock. Contact your dealer immediately.

Before cleaning this unit, turn the unit off at the power switch and disconnect the power plug from the power outlet.

Accidental operation of the unit during cleaning could result in injury.

Remove any dust that accumulates on the power plug prongs and the surface of the plug from which the prongs extend.

Accumulated dust could result in a ﬁre.

Always grip the plug when disconnecting the power plug from the power outlet.

Forcibly pulling on the power cord could cause damage, resulting in a ﬁre or an electrical shock.

Do not touch or insert foreign objects into any rotating part during operation.

This could result in injury.

CAUTION

Keep away long hair, ties, jewelry and loose clothing.

This could result in injury.

Do not put ﬁngers inside during operation.

This could result in injury.

4. HANDLING OF PAPER

4-1. Paper Used

If using folded or curled paper, flatten first prior to use.

Make sure that the printing ink on the paper has dried completely prior to use.

If used without the ink completely dried, the folding roller or paper may become dirty.

Use paper that has been cut at right angles.

If not cut at right angles, problems such as folding misalignment may occur.

Fan paper just copied or printed well prior

to use.

Paper just copied or printed contains considerable static electricity, and if not fanned well, problems such as double-feed will result.

4. HANDLING OF PAPER

Stack the paper so that the lead edge

touches the shutter gently.

I f th e r e is a ga p b e t w e en th e lead edge and shutter, the paper detection sensor will not function properly.

Do not stack paper on the paper feed tray

with the left and right sides of the paper unaligned or some sheets protruding out.

If the paper is protruding on the left or right side, the paper size detection sensor will not function normally and detect the paper size accurately.

Shutter

Stack so that there is no gap.

Paper feed tray

<Paper protruding on

Paper

<Paper protruding at

Do not stack paper on the paper feed tray

with the lead and trail edges unaligned or some sheets protruding out.

If the paper is protruding at the lead or trail edge, paper will not be fed stably, resulting in problems such as paper feed e rror and folding misalignment.

In some cases, paper may not be fed smoothly into the folding plate due to the environment (temperature, humidity), paper thickness, paper type, paper states, and processing speed, etc., and as a result, the paper may not be folded properly. In such cases, lower the processing speed, or improve the paper states before use.

1. STANDARD FOLDING OF STANDARD PAPER

1-1. Standard Paper

There are six types of standard paper sizes; A3, B4, A4, B5, A5, and B6. All these sizes are detected as standard paper only when stacked in the short edge feeding direction (direction shown in the ﬁgure).

For A4 and B5 sizes, these can be used as non-sta ndard paper e ven when stacked in the long edge feeding direction. (Refer to Chapter 3 APPLIED

Adjust the separating air amount

using the separating air adjusting knob.

The standard amount of the separating air is “2”. The larger the ﬁgure, the stronger the separating air blown will be. When using large art paper or coated paper, adjust the knob to a large value. Adjust to a small value for small and thin paper.

Adjust the separator height using the

separator adjusting knob.

The standard height of the separator is one where the separator is touching the suction belt lightly. Normally, set the knob to “2”. If mis-feed occurs, adjust the knob to a large value. If double-feed occurs, adjust to a small value.

Separating air adjusting knob

Set the thin paper feed button to

ON or OFF according to the paper thickness.

Press the button to select ON or OFF. When the lamp is lit, the thin paper function is ON. When the lamp is off, the thin paper function is OFF. Set to ON if the paper thickness is less than 81.4 g/m2.

Every time the “–” key is pressed, the speed lamp lights up towards the left and the speed decreases. When the power is turned on, the speed used the last time is displayed.

When using thin and flimsy paper, setting the speed to 5 may cause problems

such as paper jam and deformed folding. Set to lower speeds.

The speed can be set faster than 5 or slower than 1. (This setting becomes invalid

when the power is turned OFF, and when the power is turned ON again, it will be set to speed 5 or 1.)

1) Press the “+” key until the speed 5 lamp lights up.

2) Press and hold the “+” key for more than three seconds. The lamp will stop lighting and start blinking.

To return to speed 5, press the “–” key once. The lamp will start lighting.
