FOR LONG OPERATING LIFE
UNSUITABLE MATERIALS FOR THE UNIT
Many plastic components are used in the backside. Coat
flaking and deformation are likely to occur if the unit is wiped
with chemical dusters, benzine, thinner or any other sol-
vent, 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 instruc-
tion booklets for other devices connected with the Digital
monochrome printer.
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 dam-
age. Further, make sure to disconnect the power cord from
the power outlet, and the cables from the connected de-
vices.
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 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,
the print 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 nonvolatile organic solvents
(alcohol, ester, ketone, 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 place 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 antistatic coating against thermal head
damage caused by static-electricity discharge.
The use of non-treated paper may cause premature
head failure in your product.
