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
4
1. Maintenance Precautions
• This machine includes parts that must be replaced periodically. We therefore recommend taking
out a maintenance contract. Clean this machine and replace 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. Do not touch the unit until it cools down after turning
off the LED.
• 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.
• 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.

3. Maintenance Procedure

3. Maintenance Procedure
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.
lShake 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).
1On the LOCAL mode screen, select [MENU] > [Maintenance], then press the [ENTER] key.
• The Maintenance menu is displayed.
2Select [Station] > [Carriage Out] > [Station Maint.], then press the [ENTER] key.
• The carriage moves over the platen.
3Open the front cover.
3. Maintenance Procedure

4Remove the wiper.
• Hold the lugs on both sides of the wiper bracket, then pull out the wiper.
Lug
5Clean the wiper and bracket.
• Wipe off any ink and dust adhering using a cleaning stick moistened with maintenance liquid. Wipe
off the maintenance liquid. Make sure none remains.
Wiper
Bracket
• Replace dirty or warped wipers with new ones. "Wiper Replacement"(P. 19)
6Clean the wiper slider.
• Wipe off any ink and dust adhering using a cleaning stick moistened with maintenance liquid. Wipe
off the maintenance liquid. Make sure none remains.
7Reattach the wiper at the original position.

8Cleaning the wiper cleaner.
• Wipe off any ink and dust adhering using a cleaning stick moistened with maintenance liquid. Wipe
off the maintenance liquid. Make sure none remains.
Wiper cleaner
• Only clean the front side of the wiper cleaner. There is no need to clean the backside.
• Do not remove the wiper cleaner from the bracket.
• After cleaning is completed, check to confirm that the wiper cleaner is not facing up.
OKOK No goodNo good
• Soak up ink in the waste ink holder with a paper towel once a week. Doing so may result
in leaking ink.
• Do not remove the absorbent material in the absorbent material case. Doing so may result
in leaking ink.
9Once cleaning is complete, close the cover, then press the [ENTER] key.
Cap Rubber Cleaning
The cap prevents 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).
1On the LOCAL mode screen, select [MENU] > [Maintenance], then press the [ENTER] key.
• The Maintenance menu is displayed.
3. Maintenance Procedure
9
2Select [Station] > [Carriage Out] > [Station Maint.], then press the [ENTER] key.
• The carriage moves over the platen.
3Open the front cover.
4Clean the cap rubber.
• Wipe off any ink and dust adhering using a cleaning stick moistened with maintenance liquid. Wipe
off the maintenance liquid. Make sure none remains.
Cap rubber
5Check to confirm that the cap slider is not tilted once cleaning is complete.
• If the cap slider is tilted, move the slider block to the left or right to correct the tilt.
6Close the front cover, then press the [ENTER] key.
NCU Cleaning
The NCU uses a sensor to monitor the ink droplets ejected from the print head nozzles. Continuing to use
the 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).
1On the LOCAL mode screen, select [MENU] > [Maintenance], then press the [ENTER] key.
• The Maintenance menu is displayed.
2Select [Station] > [Carriage Out] > [Station Maint.], then press the [ENTER] key.
• The carriage moves over the platen.
3Open the front cover.
3. Maintenance Procedure

4Clean the NCU.
• Wipe off any ink and dust adhering using a cleaning stick moistened with maintenance liquid. Wipe
off the maintenance liquid. Make sure none remains.
• Insert the cleaning stick as far as the line shown in the illustration.
5Once cleaning is complete, close the cover, then press the [ENTER] key.
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).
1On the LOCAL mode screen, select [MENU] > [Maintenance], then press the [ENTER] key.
• The Maintenance menu is displayed.
2Select [Station] > [Carriage Out] > [Head Maint.], then press the [ENTER] key.
• The carriage moves to the maintenance space.
3Open the maintenance covers.
