PRECAUTIONS

MAINTAIN GOOD VENTILATION

Ventilation slots and holes are provided on sides of this
unit.
Place the unit on a hard and level surface and locate at
least 4" (10cm) from walls to ensure proper ventilation.

UNSUITABLE LOCATIONS

Avoid shaky places or hot-springs areas where hydrogen
sulfide and acidic ions are likely to be generated.

PLACES WITH HIGH HUMIDITY AND DUST

Do not place the unit at locations with high humidity and/
or dust. They can cause extensive damage.
Avoid places where the unit is likely to contact oily fumes
and vapors.

INSTALLATION LOCATIONS

PLACES NOT LIKELY TO BE EXTREMELY HOT

Places exposed to direct sunlight, or near heating
appliances can attain extremely high temperatures,
which may deform the cabinet, or can become a
prime cause of damage.

SET THE UNIT ON A FLAT PLACE

Do not use the unit in the state inclined ±20° in vertical or
horizontal direction, or in an unstable place.
It will disturb paper feeding or ventilation, or affects the
set.

In the interest of safety, please observe the following
precautions:

POWER REQUIREMENT

This Video Copy Processor is designed for operation on
120/220-240V AC 50/60Hz in U.S.A and Canada, 220­240V AC 50/60Hz in Europe. Never connect to any outlet
or power supply having a different voltage or frequency.

DO NOT REMOVE THE CABINET

Touching internal parts is dangerous, besides, it may
lead to malfunction. Contact the sales dealer to carry out
internal checks and/or adjustments. Before opening the
cover for eliminating a jammed paper, etc., be sure to
disconnect the power cord plug.

PLACE THE UNIT ON A HORIZONTAL LEVEL

The unit is likely to be affected if it is placed in slanted
conditions or in unstable places.

PROTECT AGAINST DEW FORMATION

In extremely cold regions, if the unit is moved quickly from
an extremely cold place to a warmer one, dew is likely to
be formed. If dew is formed, printing is not possible.

OPERATING AMBIENT TEMPERATURE RANGE

The operating ambient temperature range is 5°C-40°C
(41°F-104°F), and humidity of 20-80%.

BE CAREFUL AROUND PRINT PAPER EXIT SLIT

Do not insert your hand or any material into the paper exit
slit during printing.
Do not touch the cutter blade inside the paper exit slit.
Otherwise, your finger will be injured.

DO NOT TOUCH THE THERMAL HEAD AND CUTTER

Do not touch your hand to the thermal head (located
inside the unit) and the cutter blade.
The thermal head is heated to high temperature.
This may cause injury.

IF ABNORMALITIES ARISE, . . .

Use of the unit during emission of smoke or abnormal
sounds (without adopting countermeasures) is dangerous.
In such a case, unplug the power cord from the source
outlet immeadiately, and request maintenance services
from the sales dealer.

NEVER INSERT ANY OBJECT INTO THE UNIT

Foreign objects of any kind inserted into this unit constitute
a safety hazard and can cause extensive damage.
If any object should be inserted into the unit, unplug the
power cord, then contact the sales dealer.

DO NOT PLACE ANYTHING ON THE UNIT

Heavy objects placed on the unit can cause damage or
obstruct proper ventilation.

PROTECT THE POWER CORD

Damage to the power cord may cause fire or shock
hazard. When unplugging, hold by the plug only and
remove carefully.
Never put a heavy thing on the power cord. The cord may
be damaged causing a fire or electric shock.

DO NOT PLACE WATER CONTAINERS ON THE UNIT

Do not place flower vases, and other water-holding
containers on the unit. If, for some reason, water seeps to
the inside of the unit, unplug the power cord from the
source outlet, and contact the sales daler. If used without
corrective measures, the unit may be damaged.

PROTECTIVE MEASURES

WARNING : THIS APPARATUS MUST BE EARTHED.
AVERTISSEMENT : CET APPAREIL DOIT ETRE MIS A
LA TERRE.

This equipment is classified as class 1, type B according to
the type of protection against electric shock.

FOR LONG OPERATING LIFE

UNSUITABLE MATERIALS FOR THE UNIT

Many plastic components are used in the back-side.
Coat flaking and deformation are likely to occur if the
unit is wiped with chemical dusters, benzine, thinner or
any other solvent, if rubbers or PVC items are left in
contact with the unit for extended duration, or if the unit
is sprayed with insecticide.

CARE OF THE CABINET

Unplug and clean with a soft cloth slightly moistened
with a mild soap and water solution. Allow to dry
completely before operating. Never use petroleum base
solutions or abrasive cleaners.

HEAD ABRASION

The thermal head, like the video head, wears out.
When it is abraded, it becomes hard to print out fine
details of the picture. In such a case, it is necessary to
replace the thermal head. Consult with the sales dealer
for replacing the head.

WHEN A DEFECT IS FOUND

When you detect smoke or smell from the unit, disconnect
immediately the power cord plug from a wall socket and
ask the agent for repair. Dangerous if the unit is operated
in that state.

CONNECTION DEVICES

Read thoroughly "Operating Precautions" of the
instruction booklets for the devices connected with the
Video Copy Processor.
Do not disconnect the power cord during printing.

CAUTION ON RELOCATING

When transporting this unit, make sure it is not likely to
be subjected to impacts. They can be a prime cause for
damage. Further, make sure to disconnect the power
cord from the power outlet, and the cables from the
connected devices.

UNPLUG THE POWER CORD DURING A LONG
ABSENCE

Turn off the MAIN power switch and unplug the power
cord during a long absence.

THERMAL PAPER

2

Thermal paper K65HM (High-density synthetic
paper for high quality printing) is available.

2

One roll of K65HM permits printing about 260 pictures
in "PAPER SAVING MODE".

2

When the remaining length of the paper is about10"
(25cm), a color belt appears at the paper end.
Prepare for replacement of the paper. If the
remaining paper length is less than 10" (25cm),
printing becomes uneven due to the uneven
paper core surface.

2

When the Printed paper is touched by wet hand,
theprint may be discolored.

2

When the paper runs out during printing, the printing
operation stops and "EP" is displayed by the indicator
on the front panel. Install new paper at this time.

2

Store the printed paper in a place with low humidity
free from a direct sunlight.

2

If the paper absorbs non-volatile organic solvents
(alcohol, ester, katone, etc.) the print may be
discolored.
Particularly, if the paper comes in contact with soft
vinyl chloride such as a transparent tape, it quickens
discoloration.

2

Do not use paper other than the specified one.

2

Immediately after the paper is replaced, 2-3 images
may be printed with a blank part due to hand's dust
or oil.

2

Avoid a direct sunlight or a plane near a heater,
and store the paper in a place with 30°C ( 86°F)
or lower temperature and 35-80% RH.

2

When the paper is rapidly transferred from a cool
place to a hot place, a vapor or a dew is generated
on the paper surface causing paper jam or degraded
printing quality.

2

A finger print or dust on the paper surface may
degrade the printing quality.

Note:

Mitsubishi brand thermal paper is specially treated
with an anti-static coating against thermal head
damage caused by static-electricity discharge.
The use of non-treated paper may cause premature
head failure in your product.
