1. Introduction

1.1 Safety precautions

● Before using the printer, thoroughly read the following safety precautions for optimum printer use.

● You should observe the precautions set forth below in order to use the product properly and avoid

endangering or causing damage to you or other persons. For the purpose of clarifying the

severity of injury or damage and likelihood of occurrence, the precautions are classified into two

categories, WARNING and CAUTION, which both describe the hazardous situations that may

arise if you ignore the precautions and perform an incorrect handling or operating procedure.

The precautions in these two categories are both important and must therefore be observed

without fail.

WARNING is used to indicate the presence of a hazard which may

cause severe personal injury or death if the warning against

performing an incorrect handling procedure is ignored.

CAUTION is used to indicate the presence of a hazard which may

cause personal injury or property damage if the warning against

performing an incorrect handling procedure is ignored.

● If the warning in the CAUTION category is ignored, serious results may occur depending on the

● Ensure that there is no flame- or arc-generating device around the

printer.

The ink and makeup are both flammable and may cause fire.

Fire can be generated by matches, lighters, cigarettes, heaters, stoves, gas

burners, welders, grinders and static electricity. Arcs may be generated from

open-type relays, switches, and brush motors. Before handling the ink and

makeup, remove static electricity from your body, peripheral equipment, and so

on. In the interest of safety, position a dry-chemical fire extinguisher near the

printer.

● Since the ink and makeup contain organic solvents, install the

printer at an adequately ventilated location.

①Never install the printer in an enclosed space.

②Connect exhaust equipment to the printer in order to prevent it from filling with

organic solvent vapor.

● Do not insert tweezers, a screwdriver, or any other metal article

into the ink ejection hole in the end of the print head.

When the printer is ready to print, a high voltage (approximately 6 kV) is applied to

the deflection electrode section in the print head.

Exercise caution to avoid electric shock, injury, and fire.

● Be sure to shut off the power before replacing electrical

components (power, PC board, etc.). Be sure to unplug the power

cable from the electrical outlet before performing work with the

inlet cover and/or side cover off (terminal block transfer, EZJ113

board replacement, etc.).

Failure to do so could result electrical shock, injury or fire.

● Use an AC voltage of 100 to120 V or 200 to 240 V only and a power

frequency of 50 or 60 Hz only.

If the above requirements are not met, the electric parts may overheat and burn,

creating a risk of fire or electric shock.

● Use the power cable that is designated in this manual.

● Wire the power supply in accordance with this manual.

● Never drain the ink or makeup waste solution into a public sewer

system.

Waste disposal must comply with all appropriate regulations.

Consult the appropriate regulatory agency for further information.

● Exercise caution to avoid inadvertently disconnecting, forcibly

pulling, or bending piping tubes.

Since the ink and makeup in some portions of piping tubes are pressurized, they

may splash into your eyes or mouth or onto your hands or clothing.

If any ink or makeup enters your eyes or mouth, immediately flush with warm or

cold water and consult a physician.

● While the printer is operating, do not look into the ink ejection hole

in the end of the print head.

Ink or makeup may enter your eyes or mouth or soil your hands or clothing.

If any ink or makeup enters your eyes or mouth, immediately flush with warm or

cold water and consult a physician.

● Before servicing the printer, be sure to stop the ink ejection.

Because ink or makeup may splash into your eyes or mouth or onto your hands or

clothing. If any ink or makeup enters your eyes or mouth, immediately flush with

● When charging a refill of ink or makeup, exchanging ink, or

otherwise handling ink or makeup, take enough care not to spill

ink or makeup.

If you spill any ink or makeup by mistake, wipe it off neatly and

promptly with wiping paper or something similar. Do not close the

maintenance cover until you make sure that the portion you have

just wiped is completely dry.

You must pay particular attention when you have spilled ink or

makeup inside the printer and it is not completely dry. Why?

Because vapors of ink or makeup will stay inside the printer and

may catch on or cause a fire.

If you find it hard to wipe the printer when it is turned on, stop it with the

maintenance cover open. Power it down, and then wipe it off again.

● If you wish to clean the casing of the printer with wiping paper

impregnated with makeup, be sure to do so with the power off.

Attempting to clean it when the power is on will cause makeup or vapors of

makeup to enter the printer, possibly catching on or causing a fire.

When the cleaning is over, open the maintenance cover and make sure that no

makeup has entered and no vapors remain inside.

● Should you find a leak of ink or makeup inside the printer while the

printer is running or being maintained, wipe it off promptly with

wiping paper or something similar. Then, with the maintenance

cover open, stop the printer, power it down, and repair the leak.

Continuing operation with a leak of ink or makeup will cause an anomaly,

resulting in abnormal printing.

Ink and makeup are flammable. They may therefore catch on or cause a fire

●The ink and makeup, their waste solution, used wiping papers and

empty containers are flammable. Waste disposal must comply with

appropriate regulations. Consult the appropriate regulatory agency

for further information.

● If you wish to receive ink particles in a beaker, for a printing test for

example, use an electrically conductive beaker and connect the

beaker securely to the ground.

Do not let the tip of the printing head enter the beaker.

Ink particles used for printing are electrically charged. An ungrounded beaker has

a gradually rising charge, possibly catching on or causing a fire.

● Make sure the ground wire is properly connected to the ground

of the electrical outlet.

Failure to do so could result electrical shock or fire.
