Maintenance
To ensure years of precise performance, maintain the machine periodically based on frequency of use.
Read the maintenance precautions thoroughly before maintaining this product.

1. Maintenance Precautions
6
1. Maintenance Precautions
• This machine includes parts that must be replaced periodically. We therefore recommend taking
out a maintenance contract. Carry out maintenance periodically and replace consumable items
to prevent quality defects and accidents.
• Clean periodically. Debris and dust will accumulate on electrical components when the machine
is used for extended periods. There is a risk of failure, electric shock, or fire due to current
leakage.
• Do not clean by blowing—e.g., avoid using air blowers. Doing so may lead to failure, electric
shock, or fire involving the machine if airborne debris or dust gets inside electrical components.
Wipe using a soft cloth soaked in diluted neutral detergent and thoroughly wrung out. A vacuum
cleaner may also be used for cleaning.
• Be careful to prevent liquids from getting inside the machine. Otherwise there is a risk of failure,
electric shock, or fire.
• The UV-LED unit becomes extremely hot. Be careful not to touch the LED after it has been
turned off until it has sufficiently cooled.
• For heavy soiling, wipe using a soft cloth soaked in diluted neutral detergent and thoroughly
wrung out.
• Pay close attention to ventilation and be sure to wear safety glasses, gloves, and a mask when
handling ink, maintenance liquid, waste ink, or other solutions used with the machine. Leaking
ink may adhere to the skin or get into the eyes or mouth.
• Never touch the print head nozzle surface. Do not allow water or alcohol to come into contact
with the print nozzle surface. This will increase the risk of machine failure or ejection failures
(e.g., nozzle clogging or deflection).
• Do not use cotton swabs to clean around the head or carriage. Fibers from cotton swabs may
adhere to the head nozzle surface and lead to ejection failures (e.g., nozzle clogging or
deflection).
• Do not splash ink or maintenance liquid on the covers. Exposure to splashing ink or
maintenance liquid may damage or deform the cover.
• Do not use benzine, thinner, or any chemical agent containing abrasives. Use of these
chemicals may result in damage to or deformation of parts.
• Do not move the carriage by hand. To move the carriage, use the carriage out function on the
menu.

Ink Maintenance
If ink constituents are sedimented, the ink density may become uneven. We recommend shaking the Ink
bottle periodically to keep printing consistent.
UV ink: once a month.
UV white ink: once a day.
• This machine counts the time elapsed after stirring the white ink. The "Shake White Ink Bottle"
message appears when a preset count is reached. If the message appears, shake the white ink
bottle by following the instructions below:
When the message appears: every 24 hours (or when the power is turned on if the power was
turned off).
lShaking the Ink bottle
1Shake the Ink bottle to the left and right slowly at least 20 times.
• Tighten the ink bottle lid securely, then shake the bottle slowly from left to right to ensure that the
ink moves inside, holding the ink bottle lid with a paper towel.
Repeat
• Shake slowly. If the bottle is shaken too violently, ink may leak out or the air mixed in the
ink may cause nozzle clogging.
• If the ink bottle is partially used, tilt it slowly until the ink bottle is upright.
White Ink Maintenance
White ink constituents are more easily sedimented than other ink colors. If ink constituents are sedimented,
the ink density may become uneven. Perform maintenance once a week as follows before using the
machine.
