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

1. Maintenance Precautions
4
1. Maintenance Precautions
• This product contains components that must be replaced periodically. We recommend
concluding a maintenance contract.
• Maintain this product and replace consumable items to prevent quality defects and accidents.
• Clean periodically. Debris and dust will accumulate on electrical components when this product
is used for extended periods. Current leaks may result in failure, electric shock, or fire.
• Do not clean by blowing—e.g., avoid using air blowers. Doing so may lead to failure, electric
shock, or fire involving the product if airborne debris or dust gets inside electrical components.
Wipe away debris or dust using a soft cloth soaked in water and thoroughly wrung out. A
vacuum cleaner may also be used for cleaning.
• Do not allow liquids to get inside the product. Ingress of liquids into the product may lead to
failure, electric shock, or fire.
• For heavy soiling, wipe using a soft cloth soaked in dilute detergent and thoroughly wrung out.
• Wear safety glasses, gloves, and a mask when handling ink, maintenance cleaning solution,
waste ink, or other solutions used with this machine. Leaking ink may adhere to the skin or get
into your eyes or mouth.
• Avoid touching the print nozzle surface. Do not allow water or alcohol to come into contact with
the print nozzle surface. Contact with water or alcohol may lead to failure or print defects (e.g.,
nozzle clogging, deflection).
• Avoid using cotton swabs to clean around the head or carriage. Fibers from cotton swabs may
adhere to the head nozzle surface and lead to print defects (e.g., nozzle clogging, deflection).
• Be careful to avoid splashing ink or washing liquid on the covers. Exposure to splashing ink or
washing liquid may damage or deform the cover.
• Avoid using chemical products containing benzine, thinner, or 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.

• Do not store in places accessible to children.
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.
lWhite Ink
This product counts the time elapsed after stirring the white ink Ink bottle. The “Shake White Ink Bottle”
message appears when a preset count is reached. If the message appears, shake the Ink bottle by following
the instructions below:
• Timing 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 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, flip the Ink bottle upright and shake slowly at an angle.
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.
1Shake the white ink Ink bottle.
• "Ink Maintenance"(P. 6)
2Close the front cover.
• Be sure to close the front cover. Ink stirring starts.

• The Maintenance menu is displayed.
4Select [White Maintenance], then press the [ENTER] key.
5Remove the media, then press the [ENTER] key.
6Press the [ENTER] key.
• Discharging/filling/cleaning starts automatically.
• The elapsed time is displayed.
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 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 print defects (e.g., nozzle clogging, deflection).
1In LOCAL mode screen, select [MENU] > [Maintenance], then press the [ENTER] key.
• The Maintenance menu is displayed.
2Select [Station] > [Carriage Out] > [Move To Platen Right End ], then press the [ENTER] key.
• The carriage moves over the platen.
3Open the front cover.

5Clean the wiper and bracket.
• Wipe off any ink adhering to the wiper and bracket using a cleaning stick moistened with washing
liquid.
• Wipe off the washing liquid. Make sure none remains.
Wiper
Bracket
• Replace dirty or warped wipers with new ones.
"Wiper Replacement"(P. 19)
6Reattach the wiper at the original position.
Lug
• Do not remove the absorbent material in the absorbent material case. Doing so may result
in leaking ink.
7Once cleaning is complete, close the front cover, then press the [ENTER] key.
Cap 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 print defects (e.g., nozzle clogging, deflection).
1In LOCAL mode screen, select [MENU] > [Maintenance], then press the [ENTER] key.

• Wipe off any ink adhering to the cap rubber using a cleaning stick moistened with washing liquid.
• Wipe off the washing 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.
6Once cleaning is complete, close 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 recovery function from operating correctly.
• Be careful to avoid leaving fragments from the cleaning stick behind when cleaning. These
fragments will increase the risk of print defects (e.g., nozzle clogging, deflection).

Insert to this line
5Once cleaning is complete, close the front 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 print defects (e.g., nozzle clogging, deflection).

and deflection) or other faults.
• Do not leave media loaded on the platen. This may leave irregularities or ripples in the media.
• When this product is not in use, raise the clamp lever to separate the pinch rollers from the grid
rollers. If the pinch rollers are left in the lowered position for an extended period of time, they
may become deformed, possibly preventing the media from being fed correctly.
