●Safety Precautions (3)
SAFETY PRECAUTIONS (Continued)
WARNING
●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.
Never install the printer in an enclosed space.
Connect exhaust equipment to the printer in order to prevent it from filling
with organic solvent vapor.
Secure adequate space for the ink/makeup handling area and printer
installation site. At least 400 m must be provided per print head.
Ensure that adequate ventilation is provided.

CAUTION
●If extraneous noise enters the printer, it may malfunction or break down.
For maximum noise immunity, observe the following installation and wiring
precautions.
Ensure that 100 to 120 VAC or 200 to 240 VAC power cables are not
bundled with other power supply cables.
Insulate the printer main body and print head so that they do not come into
direct contact with the conveyor or other devices.
If 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.
Be sure that the print target detector wiring is not bundled together with other
power supply cables.

(4) ●Safety Precautions
SAFETY PRECAUTIONS (Continued)
WARNING
●Ensure that all electrical wiring, connections and grounding comply with
applicable cords. Properly connect the printer to its dedicated ground.
Complete the above procedure to avoid electrical shock hazards.
●When welding, keep enough space between the IJ printer and the
welding work area to prevent the arc from starting a fire. Also, be sure to
insulate the printhead and IJ printer frame to keep the welding current
from flowing to the control section of the printer, and to make a separate
ground connection for the printer.
●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.
Grounding
WARNING
●Use an AC voltage of 100 to120 V or 200 to 240 V ±10% 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.

●Safety Precautions (5)
SAFETY PRECAUTIONS (Continued)
Ink and Makeup Handling
WARNING
●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.
CAUTION
●Since the ink and makeup contain organic solvents, observe the following
handling precautions.
When handling the ink or makeup, wear protective gloves and safety goggles to
avoid direct skin contact. If the ink or makeup comes into contact with skin, wash
thoroughly with soap and warm or cold water.
When transferring the ink or makeup to or from a bottle, exercise caution to
prevent it coming into contact with the printer or surrounding articles.
If there is any spillage, immediately wipe it clean using a cloth moistened with
makeup.
●Ink and makeup must be stored as flammable liquids. Storage must comply
with local regulatory requirements. Consult the appropriate regulatory
agency for further information.

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.
Never install the printer in an enclosed space.
Connect exhaust equipment to the printer in order to prevent it from filling with
organic solvent vapor.
WARNING

1
(1) Provide a clearance around the IJ printer for daily operation,
handling, and maintenance access (see the figure at right).
(2) The print head needs to be cleaned with the makeup while the
printeris operatedandstopped (daily maintenance). Adopta fixed
structure in consideration of print head cover and print head
removal.
(3) Installation must be completed so that no vibration will be applied to
the IJ printer main body, print head, or print head cable.
If they are vibrated, print quality deterioration and print irregularity
may be incurred (the maximum permissible vibration value is
1.96m/s ).
(4) The IJ printer main body must be installed with a levelness error of
not over ±1°.
(5) The IJ printer main body must be electrically insulated from the
other equipment (conveyors, packing machines,etc.), photoelectric
switches, and the rotary encoder.
(6) The standard distance between the printing head and the object to be
printed on is as indicated in the right-hand table.
The smaller the clearance between the print head and print target,
the smaller the character height and the better printing.
(7) The IJ printer proper requires maintenance as the occasion may
demand including replenishment of ink and makeup and
replacement of filter.
(8) If ambient humidity is 85 to 90%RH, you must purge inside of print
head by air. It is necessary for dry-clean air, regulator for pressure
of air and air filter. (Quantities of the air are 1L / minutes.)
* Leave a maintenance area of
at least 20 cm for the upside
of printer.

(9) When installing the print head and print head cable, comply with the following conditions or it will
increase the risk of degraded performance of the ink supply and ink recovery behavior.
When positioning the end of the print head above the printer main body installation surface,ensure
that the distance between the end of the print head and the installation surface does not exceed 1.5 m.
When positioning the end of the print head below the printer main body installation surface, ensure
that the distance between the end of the print head and the installation surface does not exceed 1 m.

Print head
Print head cable
Bend R 0.5m
(10) When using the printer for upward or lateral printing, ensure that the rising print head cable upper end
is positioned not more than 0.5 m above the print head.
(11) If you fixed the print head, ensure that the minimum bend radius of the print head cable is at least 150 mm.
Handle the headcable with care when wiring it.
If the minimum bend radius is less than 150mm, the tubes and wires inside the headcable might be broken.
(12) The ink stream may bend for some reason or other (due, for instance, to dirt).
The facilities positioned in the direction of ink ejection should be partially covered as needed to avoid ink
accumulation.

2-3 ●Installing Precautions
(14) If you try to fix the print head with a magnetic substance (such as iron), the cover switch will
malfunction resulting in an "Cover Open" error.
This, you must only use nonmagnetic resins or metals for fixing the print head.
(15) In the case of carrying the printer proper, use the handles in the drawing below.
Connect a duct to this port
(50 mm in diameter).
Exhaust duct
connection port
(13) When connecting an exhaust duct to the printer, install a damper and adjust the wind velocity at the intake
port to 0.3 to 0.5 m/s. (Use an anemometer for verification. If the wind velocity is too high, the makeup
consumption increases.)

●Print head air purge 3-1
3.1 Print head air purge
If the makeup remains in the electrode section after cleaning or if you use the IJ
printer at a high humidity, moisture condensation may occur within the print head,
causing leakage from the deflection electrode section. It is also important to
remember that dust or splashed ink accumulation on the deflection electrode
section may cause leakage. Performing the following air purge procedure for the
print head interior is effective in preventing such leakage.
3. INSTALLATION CHECK ITEMS
If the air-purge amount is excessive, print irregularities may occur.
After air-purge pressure adjustment, be sure to perform a printing test to
verify the printing results.
(1) Situations requiring an air purge
When the printer is used in a highly humid place such as a beer or other beverage can line
(If you use the printer in an environment in which the relative humidity is 85% or higher,
complete the print head air-purge procedure).
When a water drainage blow sequence is performed before printing.
When the printer is used in a place where a considerable amount of paper powder or other dust
exists.
When the printing distance is short so that the end of the print head is splashed with ink.
When you use inks that are indicated on the handling guidance of each ink to complete
air-purge procedure.
(2) Air-purging procedure
Introduce clean dry air into the print head air purge connection port (Rc 1/8 (PT 1/8)×screw) in
the rear of the printer main body at a pressure of about 0.1 to 0.3 MPa. If it is possible that the
employed air tanks oil or water, turn it into clean dry air with an air filter, micro-mist separator, or
the like before introducing it into the printer main body.
