Maintenance
To ensure years of precise performance, maintain this product 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. We recommend cleaning this machine and replacing consumable
items to prevent quality defects and accidents.
• Clean periodically. Debris and dust will accumulate on electrical components when this 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 dilute detergent and thoroughly wrung out. A vacuum cleaner
may also be used for cleaning.
• Do not allow liquids to get inside the product. 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 dilute 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 this 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 printing defects
(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 printing defects (e.g., nozzle clogging or
deflection).
• Be careful to avoid splashing ink or maintenance liquid on the covers. Exposure to splashing ink
or maintenance liquid may damage or deform the cover.
• Avoid using 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.

3. Performing Maintenance
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.
White ink: once a day.
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 the procedure.
• 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.
Wiper Cleaning
The wiper wipes off ink adhering to the print head nozzle surface. Continuing to use the dirty wiper may
cause the wiper to which dried ink and dust are attached to rub against the nozzle surface, leading to printing
defects (e.g., nozzle clogging or deflection).
• Be careful to avoid leaving fragments from the cleaning stick behind when cleaning. These
fragments will increase the risk of printing defects (e.g., nozzle clogging or deflection).

7Tap [Complete] > [Finish] once cleaning is complete.
Cap Rubber Cleaning
The cap rubber keeps the print head nozzle surface from drying out. Continuing to use a dirty cap may affect
ink take-up and lead to print defects (e.g., nozzle clogging, deflection).
• Be careful to avoid leaving fragments from the cleaning stick behind when cleaning. These
fragments will increase the risk of printing defects (e.g., nozzle clogging or deflection).

deflection).

5Tap [Complete] > [Finish] once cleaning is complete.
NCU Cleaning
The NCU uses a sensor to monitor the ink droplets ejected from the print head nozzles. Continuing to use a
dirty NCU may prevent the nozzle check function from operating correctly.
• Be careful to avoid leaving fragments from the cleaning stick behind when cleaning. These
fragments will increase the risk of printing defects (e.g., nozzle clogging or deflection).

• Insert the cleaning stick as far as the line shown in the illustration.
4Tap [Complete] > [Finish] once cleaning is complete.
Carriage Underside Cleaning
The underside of the carriage becomes coated with ink wiped off by the wiper. Continuing to use the dirty
carriage underside will rub dried ink and attached dust on to the media, resulting in contaminated prints.
The print head uses an extremely delicate mechanism. Take great care when handling it.
• Be careful to avoid leaving fragments from the cleaning stick behind when cleaning. These
fragments will increase the risk of printing defects (e.g., nozzle clogging or deflection).

Table Cleaning
Continuing to use the dirty table will cause dried ink and attached dust to rub against the head nozzle
surface, resulting in print defects (e.g., nozzle clogging, deflection). Ink left adhering to the table for extended
periods will be hard to remove, even with ethanol or solvents.
• Turn off the main power before performing maintenance tasks.
Remove dust or any solid materials frequently, using soft brush, dry cloth, or paper towel.
Dust and debris will accumulate on parts such as the table grooves and screw holes. Use a soft bristle brush
to remove dust and debris.
• For heavy soiling, wipe using a soft cloth soaked in dilute detergent and thoroughly wrung out.
• Do not allow liquids to get inside the product. Otherwise there is a risk of failure, electric shock,
or fire.
Exterior Cleaning (e.g., cover, Y-bar, )
• Turn off the main power before performing maintenance tasks.
• For heavy soiling, wipe using a soft cloth soaked in dilute detergent and thoroughly wrung out.
