SAFETY PRECAUTIONS (Continued)
Installation Environment of Printer
● 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.
③ Secure adequate space for the ink/makeup handling area and printer
installation site. At least 400 m
● If extraneous noise enters the printer, it may malfunction or break
down.
For maximum noise immunity, observe the following installation and
wiring precautions.
①Ensure that 100 to 120 VAC or 200 to 240 VAC power cables are not bundled with
other power supply cables.
②Insulate the printer main body and print head so that they do not come into direct
contact with the conveyor or other devices.
③If the employed print target detector is housed in a metal case, use a plastic
mounting brace for the purpose of insulating the detector from the conveyor and
other devices.
④Be sure that the print target detector wiring is not bundled together with other power
supply cables.
● Use the printer in an ambient temperature prescribed for each nozzle
diameter and ink and 30 to 90%RH (no condensation) environment.
①When using the printer in 85 to 90%RH environment, air purge the print head.
②Using the printer outside the specified conditions may cause abnormal printing and
erroneous operation and trouble.
