CAUTION
About UV light
• There is some leaking of ultraviolet radiation around the UV irradiation device.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.
• Impairment of eyes caused by UV light may be:Acute disorders ... Pain in eyes, tearing,etc.Chronic disorders ...
Cataract, etc.
When using this device, take protective measures such as gloves, long-sleeve cloth, light-resistant mask,
attached light-resistant glasses, etc.
About hot parts
• The UV lamp and the interior of the UV irradiation device will have a very high temperature.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.
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 time-
change components.
About firing and smoking
• Touching hot parts such as the UV irradiation device with combustible materials may cause firing and/or
smoking.
Leaving combustible materials under the UV irradiation device 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.
Notes on UV irradiation device
• When handling the UV lamp 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
UV lamp or silica glass is contaminated,wipe it with clean gauze moistened with alcohol.(Do not use alcohol for
cleaning the exteriorcover,or the paint will peel off.)
• Securely mount the UV lamp to the socket,or the lamp may be dropped or overheated.
• The UV lamp 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.
