Installation environment

S４
Safety Precautions (Continued)
WARNING
●Ensure that all electrical wiring, connections, and grounding comply with applicable
cords. Properly connect the product to its dedicated ground.
Complete the above procedure to avoid electrical shock hazards.
●When welding, keep enough space between the product and the welding work area to
prevent the arc from starting a fire. Also, insulate the print head and product frame to
keep the welding current from flowing to the control section of the product, and make
a separate ground connection for the product.
●If you need to receive ink particles in a beaker, 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.
WARNING
●Use an AC power cable within the following range:
- When using an inlet: 100 to 200 VAC
- When using a power-receiving terminal block: 100 to 200 VAC/200 to 240 VAC
- Frequency: 50 or 60 Hz
If the above requirements are not met, the electric parts may overheat and burn,
causing a fire or electric shock.
●The power cable connected by default is for 100 VAC only.
Do not modify it to a power plug for 200 VAC.
●When the power cable outlet is not used, ensure that it is connected to the input port
inside the product.
- If it is connected to an incorrect input port, the electric parts may break down,
overheat, or burn, causing a fire or electric shock.
- The supplied cable with a three-pole plug is for 100 VAC only.

Safety Precautions (Continued)
WARNING
●When handling ink or makeup, such as replenishment or replacement, 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. This is because vapors of ink or makeup will stay
inside the product and may catch on or cause a fire.
If you find it hard to wipe the printer with the power on, stop it with the maintenance
cover open. Power it down and then wipe it off again.
●If you need to clean the casing of the product with wiping paper soaked with makeup,
be sure to do so when the power is off.
Attempting to clean it with the power on will cause makeup or vapors of makeup to
enter the product, possibly catching on or causing a fire.
When the cleaning is finished, 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 product while the product is
running or being maintained, wipe it off promptly with wiping paper or something
similar. Then, with the maintenance cover open, stop the product, power it down,
and repair the leak. Otherwise, contact your nearest local distributor.
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.
●Ink and makeup, their waste solution, used wiping paper and empty containers are
flammable.
Make sure that these waste disposals are kept away from a flame or arc.

Safety Precautions (Continued)
CAUTION
●When cleaning the product or replenishing 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 from coming into contact with the product or surrounding articles. If there is any
spillage, immediately wipe it to clean using a cloth moistened with makeup.
Ink and makeup handling (continued)

S７
Safety Precautions (Continued)
WARNING
●Do not insert tweezers, a screwdriver, or any other metal article into the ink ejection
hole at the end of the print head.
When the product 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.
●Do not remove covers and/or screws not specified in this manual.
A high voltage is applied to some sections of the product.
Exercise caution to avoid electric shock and injury.
●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 product is operating, do not look into the ink ejection hole at 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.
●Make sure that there is no one in the ink ejection direction before starting the
product.
Operate with the end of the print head inserted in a beaker, etc.
●Before servicing the product, be sure to stop the ink ejection.
This is 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 warm or cold
water and consult a physician.
●If an earthquake, fire, or other emergency occurs while the printer is engaged in
printing or just turned on, press the main power switch to turn off the power.
