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.
ii
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.
iii
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.

1-2. Double Folding Thick Paper
When folding fine quality thick paper 28 lb into four, its folding section may open when ejected to the
stacker because of the paper thickness and consequently the folded paper may not be able to pass
through the stacker rollers, resulting in paper jam. To prevent this, follow the procedures below.
Do not fold fine quality thick paper 34 lb into four because paper ejection problem may
occur.

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
en
vironmental conditions (temperature, humidity), paper size and paper fiber direction.
This is not a malfunction of the machine.

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.
