About UV light
• A little UV light leaks from the LED UV unit. UV light
applied to your skin might cause inflammation and/or
skin cancer. Though weak UV light might cause no
inflammation, repeated exposure to it may lead to
chronic disorders.Avoid applying UV light to your skin
and eyes.
• The floor may be discolored because of UV light
leakage, please install the printer unit on the mat for
shielding the light.
• Possible damage to your eyes due to ultraviolet is
acute disorder (feeling like something is in your eye,
pain and flow of tears) and chronic disorder (cataract
etc.). When using this machine, take protective
measures such as gloves, longsleeve cloth, light-
resistant mask, attached UV goggle, etc.
About hot parts
• The LED UV unit become very hot. When carrying out
maintenance, wait until the temperature has been
sufficiently lowered after the lamp is turned OFF.
• Some parts outside the unit will have a very high
temperature.A hightemperature caution label is placed
on such parts.Do not touch the parts with the caution
label placed and their vicinity, or burn injury may occur.
• When it is unavoidable to touch hot parts, be sure to
wear heat-insulating gloves to protect your hands.
Notes on LED UV unit
• When handling the LED UV or the silica glass on the
bottom of the irradiation device, be sure to wear the
gloves attached and never touch them with bare
hands, or the UV ink curing level is significantly
lowered. If the LED UV or silica glass is contaminated,
wipe it with clean gauze moistened with alcohol.(Do
not use alcohol for cleaning the exterior cover, or the
paint will peel off.)
• The LED UV performance and service life are
significantly affected by the UV irradiation and UV
power supply units used. Never use those UV devices
other than those recommended by Mimaki. We would
take no responsibility for any troubles caused through
the use of a UV devices not recommended by Mimaki.
CAUTION
Lay a mat
or fabric on the floor.
About cleaning
• After using the unit long time, foreign materials and
dust may be gathered on the conductive and insulating
parts, causing electric leakage.Periodically clean such
parts.
• For cleaning, do not use compressed air because it
scatters foreign materials and dust, which may cause
malfunctions when put inside the conductive parts.Be
sure to use vacuum cleaner for cleaning of foreign
materials and dust.
• Do not use the unit in a place where there is a
possibility of being wet, or electrical leakage may
occur.
• Electrical leakage, if it should occur, may lead to
electrical shock of personnel or fire.
• In order to prevent accidents from occurring, be sure to
carry out periodic inspections and replacement of
timechange components.
About firing and smoking
• Touching hot parts such as the LED UV unit with
combustible materials may cause firing and/or
smoking. Leaving combustible materials under the UV
LED unit for a couple minutes may also cause firing
and/or smoking.
• After the unit is used long time, foreign materials or
dust gathered on the stabilizer or other parts may
cause electrical leakage or insulation deterioration
may cause firing and/or smoking.Periodically clean the
parts and measure the insulation resistance, replacing
deteriorated parts, if any.
• After the unit is used long time, screws, etc. on the
conductive parts may be loosened, causing firing and/
or smoking.Periodically tighten such screws.
• Because this unit is not of explosion proof type,do not
use it in an ambience with hazardous materials, or a
possibility of explosion may arise.
• If abnormalities of the unit such as a strange odor, a
smoking or a spark burn are found, turn the power off
and call Mimaki immediately.
