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

2When 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.

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

2When 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. Store the printed paper in a place with low humidity free from a direct sunlight.

2If 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.

Do not use paper other than the specified one.

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

2Avoid 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.

2When 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.

2A 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.
