Warning Labels
CAUTION
Never look at the blue-white (ultraviolet)
light emitted from the print-head area for an
extended time.
Looking directly at the ultraviolet light from up
close for an extended period may result in eye
injury.
Caution: Ultraviolet Light
This machine is tted with covers to keep external leakage of ultraviolet light at low levels, but incorrect
handling or operation can lead to physical injury due to ultraviolet light. The extent of injury depends
on the intensity and wavelength of the ultraviolet light, and the length of time of exposure. Prolonged
exposure to strong ultraviolet light of hazardous wavelengths can cause injury to the eyes or skin. Exercise
caution.
Warning Labels
This machine uses ultraviolet light

Important Points
To Ensure Safe Work
Turn off the sub power switch and main power switch, and unplug the power cord of the printer and
deodorization equipment before performing parts replacement. Performing the parts replacement while the
power is on may result in injury due to the unexpected operation of the printer.
Always use the UV protection sheet when the ink line is exposed to the light* during the replacement, or ink will
harden and clog in the ink line. And it will a󱐯ect the condition of a machine.
*The light means the light which includes the ultraviolet light. Consider that most of the light including
uorescent light includes the ultraviolet.
Use rubber gloves to prevent direct contact with the skin.
Contact with the ink may cause skin irritation.
Use deodorizing mask with activated carbon when necessary. When you carry the parts which are stained with
ink such as head or damper, put these parts into a bag (for example aluminum bag of ECO-UV INK) or container
that has a sealing capability. Current leakage may cause electrical shock, electrocution, or combustion and re.
Otherwise, you might feel sick because of the evaporated ECO-UV INK.
Wear protective goggles when turning on the UV Lamp without covers and when replacing the heads.

Important Points
Static electricity can harm some electronic devices. To prevent static damage, discharge static electricity from
your body before you touch any of the electronic parts. You can do so by touching an unpainted metal surface
on the chassis.
We also recommend that you take the following steps to prevent damage from electrostatic discharge (ESD):
zWhen unpacking a static-sensitive device from its shipping carton, do not remove the device from the an-
tistatic packing material until you are ready to install the part to the printer. Just before removing the anti-
static packaging, be sure to discharge static electricity from your body.
zWhen transporting a static-sensitive part, rst place it in an antistatic container or package.
zHandle all static-sensitive parts in a static-safe area. If possible, use antistatic floor pads and workbench
pads.
