● 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.
①
Never install the printer in an enclosed space.
②
Connect 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.
