1.3 Installation Precautions

Installation Precautions
Ensure that there is no flame- or arc-generating device within a distance of 5 m to
the printer.
The ink and makeup ink are both flammable and may cause ignition or fire.
Flames can be generated by matches, lighters, cigarettes, heaters, stoves,
gas burners, welders, grinders, and static electricity. Arcs may be produced
by open-type relays, switches, and brush motors. Before handling the ink
and makeup ink, remove electricity from your body, the peripheral
equipment, etc. In the interests of safety, provide a dry-chemical fire
extinguisher near the printer.
Since the ink and makeup ink contain organic solvents, install the printer at
a location where adequate ventilation (air exhaust) is provided.
1 Never install the printer in an enclosed space.
2 Connect the printer to exhaust equipment in order to prevent
accumulation of organic solvent vapors.
The ink and makeup ink contain organic solvents.
Provide adequate space for the ink/makeup ink handling area and printer
installation site. A space of at least 200 m
per print head. Ensure that adequate ventilation is provided.
Follow all regulations in your country.
1. Provide adequate space around the IJ printer for
daily operation, handling, and maintenance access
(see figure at the right).
2. The print head has to be cleaned with makeup ink
while the printer is operated and stopped (daily
maintenance). Adopt a fixed structure in considera-
tion of print head cover and print head removal.
3. Installation must be completed so that no vibration
will be transferred to the IJ printer main body, print
head, or print head cable. Vibration may cause print
quality deterioration and print irregularity (the
maximum permissible vibration level is 1.96 m/s
4. The IJ printer main body must be installed level with
a deviation of not more than ± 1°.
5. The IJ printer main body must be electrically
insulated from other
packing machines, etc.), photoelectric switches,
and the rotary encoder.
6. The standard distance between the print head and
the target to be printed is as indicated in the right-
hand table. The smaller the clearance between the
print head and print target, the smaller the
character height.
7. The IJ printer itself requires proper maintenance as
the occasion may demand including replenishment
of ink and makeup ink and replacement of the filter.
8. If ambient humidity is between 85 and 90 % RH, you must purge the interior of print
head by air. You will require dry-clean air, a pressure reducing valve and an air filter.
(Amount air required: 1l / minute.)
9. When installing the print head and print head cable, the following conditions must
be met.
