CAUTION
Notes on LED UV unit
About cleaning
• 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.)
• 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.
• 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.
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.
