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.
• 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
cartridge periodically to keep printing consistent.
Solvent ink: once a month.
Orange ink: once a week.
lOrange Ink
The "Shake Orange ink cartridge" message appears every 24 hours. When this message appears, shake the
orange ink cartridge.
lShaking the Ink cartridge
1Shake the Ink cartridge to the left and right slowly at least 20 times.
• Shake the case slowly from left to right to ensure that the ink moves inside.
Repeat the procedure.
• If the ink cartridge is partially used, cover the gap between the side and the ink cartridge
opening with a paper towel and shake slowly at an angle until the ink cartridge becomes
upright.
Needle slot Gap on the side
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 ejection failures (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] > [Move To Platen Right End], then press the [ENTER] key.
