Safety Precautions In this manual, operations and handling of the unit which are hazardous are described using the following marks to prevent personal injury or property damage to the user and others.

Ignoring this mark could result in the possibility of serious injury or even death.

Ignoring this mark could result in the possibility of injury or physical damage.

This mark indicates a “Warning” or “Caution”. A graphic may be shown inside the mark to describe the warning or caution more specifically.

This mark indicates a forbidden action. A graphic may be shown inside the mark to describe the forbidden action more specifically.

This mark indicates actions that must be performed. A graphic may be shown inside the mark to describe the action to be performed more specifically.

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 : 120 V AC, 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) : 0.85 A ● The equipment must be reliably connected to an earthed main socket-outlet.

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 41 and 95°F (14 to 122°F in storage) ● where the humidity range is between 20 and 85% 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

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.

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.

ii

Safety Precautions

Maintenance / Other

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 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.

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.

5. Handling Paper 5-1. Paper Used

● 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.

● If curled paper is used, depending on the environmental condition (temperature, humidity), paper quantity, paper type, and paper fiber, it may not flow smoothly into the folding plate or may not be folded properly. Flatten the paper prior to use.

● Fan paper well prior to use.

5-2. Precautions on Stacking Paper

● Do not stack paper on the paper feed table with the left and right sides of the paper unaligned or some sheets protruding out.

● Do not stack paper on the paper feed table with the lead and tail edges unaligned or some sheets protruding out. If the paper is protruding at the lead or tail edge, paper will not be fed stably, resulting in problems such as paper feed error and folding misalignment.

● The maximum paper thickness is 28 lb. However, this thickness may differ slightly according to various conditions such as environmental conditions (temperature, humidity), paper size, and paper fiber direction. ● When the paper is cross folded, Σ folding (folding slippage in the horizontal) and folding misalignment along sides of paper may occur due to conditions such as environmental conditions (temperature, humidity), paper size and paper fiber direction. This is not a malfunction of the machine.

Chapter 5 CLEANING THE UNIT

1. Cleaning Each Section The adherence of paper dust and printing ink on the rubber rolls and paper feed rings may cause problems such as paper feed errors and folding misalignment. Adherence of paper dust near sensors will also cause misdetection. Clean the machine once a week. We recommend that you use a commercially-available air duster for office equipment to clean sensors.

● Prior to cleaning, be sure to disconnect the power cord from the outlet. ● After cleaning, make sure that the areas that were cleaned are completely dry before resuming paper folding operations.

Do not use flammable sprays or solvent inside or near the unit (e.g. when cleaning the unit). Such flammable gas may ignite and cause a fire or combustion. Take precautions against fire and ensure ventilation when using alcohol, and store the alcohol in a safe place after use. Also note that use of other solvents can damage the rubber rollers and resin inside the unit, resulting in malfunctions.
