1. SAFETY PRECAUTIONS

Always observe the cautions and warnings given below to prevent personal injury or property damage.

The degree of danger and damage that could occur is indicated on two levels by the following marks.

WARNING : Ignoring this mark could result in the possibility of serious injury or

even death.

CAUTION : Ignoring this mark could result in the possibility of injury or physical

damage.

The following graphic symbols indicate the various types of action to be performed or avoided.

This graphic symbol indicates a forbidden action.

means “Do not disassemble.” means “Do not touch.”

This graphic symbol indicates actions that must be performed.

means “Disconnect the power plug.”

WARNING:

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 touch or insert foreign objects into any rotating part during operation. This could result in injury.

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.

Use only the power supply voltage specified on the main nameplate. Using other voltages could result in a fire or an electrical shock.

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 use solvent inside or near the unit (e.g. when cleaning the unit). Such solvents may damage the rubber rollers and resin inside the unit, resulting in malfunctions.

(Continued on the next page)

SAFETY PRECAUTIONS (continued)

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.

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.

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.

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.

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.

CAUTION:

Do not handle the power plug with wet hands. This could result in an electrical shock.

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.

Do not touch the power switch with wet hands. Otherwise electric hazards may occur.

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.

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.

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.

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.

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.

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.

Caution Label Location

The caution label is pasted on the unit to ensure the safety of users. Do not remove nor change it.

NoteNote

If the label becomes dirty, damaged, or lost, be sure to contact your nearest dealer for a new one.

2. INSTALLATION PRECAUTIONS

2-1. Installation Location

Install the unit on a table which can tolerate its weight. The mass of the unit is as follows.

96 lb

Install the unit close to a power outlet. The unit may make loud sounds while operating according to the processing speed and paper

used due to its paper-folding mechanism. Therefore install it where it will not disturb the office environment.

Refer to “1. SAFETY PRECAUTIONS” (

☞

p.3, 4).

2-2. Precautions in Moving the Unit

As the unit weights 96 lb, when moving it, it should be held at the base by two persons. When moving the unit with folding plates 1 and 2 removed, make sure the folding plates are not

subject to shock. Otherwise, the folding plates may damage, resulting in poor folding accuracy. Arrange the power cord carefully so that it does not get stepped on, and damage as a result.

3. USAGE PRECAUTIONS

3-1. Power Supply

This equipment 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.

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 power of this equipment: 1.4 to 0.7 A (95 W)

3-2. Operating Environment

Operate this unit in the following environment:

– where the temperature range is between 41 and

95°F,

– where the humidity range is between 20 and

80% RH (no dew condensation),

– which is not subject to direct sunlight,

– which is subject to little or no vibration, – where there are no harmful chemicals, – which is reasonably free from dust, – which is free from air-borne salt, and – where the equipment is not exposed to water.

3-3. Storage Conditions

Store this unit in the following environment:

– where the temperature range is between 14 and

122°F,

– where the humidity range is between 10 and

85% RH (no dew condensation),

– which is not subject to direct sunlight,

3-4. Maintenance

To protect the special features of this unit, the customer should never apply oil or grease to the parts. Please contact your dealer in case of any problem.

WARNING

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. Such solvents may damage the rubber rollers and resin inside the unit, resulting in malfunctions.

Folding mode key

If the position of the folding stopper has been finely adjusted in standard folding operations, the adjustment value can be registered with this key. A total of 30 different adjustment values can be registered (6 standard folding modes × 5 standard paper sizes). The registered data is preserved even after the power is turned off. To erase the registered data, select the paper size and folding mode to be erased. Next press this key until the buzzer sounds “pi.pi...” for about two seconds, and then press it continuously for another two seconds until the buzzer sounds “pi...”. (Four seconds in total)

Press to register the position of the folding stopper and stacker roller which have been moved when using custom folding modes. Up to two individual paper folding modes can be registered for custom folding. The registered data is preserved even after the power is turned off. To erase the registered data, continue pressing the custom folding registration key “1” or “2” registering the data to be erased until the buzzer sounds “pi...”.

When this lamp is lit, it means that the custom folding mode is registered. The custom folding mode cannot be selected if it has not been registered with the !1 Custom folding registration key.

Press to select the folding mode from six standard folding modes. When the power is turned on, the lamp of the single-folding mode lights up. Each time this key is pressed, the folding mode lamp lights up in order towards the right.
