Improvement of print quality
Cleaning suction cap
(1) Wipe the rubber seal and lip of the suction cap with one side of the tip portion of clean stick R in parallel with the
seal.
<IMPORTANT>

Clean the lip part of the suction cap carefully with clean stick R. The print head dries and causes an ejection failure if
solidified ink remains.

Do not touch the sponge of the suction cap. The sponge may come off.

Never touch the tip end of clean stick R with your hand. If any sebaceous matter is attached to the wiper, it may result in a
printer malfunction.

The clean stick R used for cleaning the nozzle guard, wiper, and exhaust cap should be rinsed in the cleaning cup before
the next use. Be sure to use the clean stick R separately for color ink and white ink.

(2) When an ink clot comes to the surface, pinch it with tweezers and remove it.
<IMPORTANT>

Be sure not to pinch the rubber seal. If it is damaged, its sealing property will be degraded, which in turn may lead to
non-ejection of ink-jet droplets from the print heads.
(3) Replace the clean stick R with a new one, rinse the cleaning cup, and clean the nozzle guard of the color side
head.
<IMPORTANT>

Be sure to use the clean stick R separately for white ink and color ink.

The used clean stick R should be disposed of, and should not be reused.

After cleaning the nozzle guard of the color side head, rinse the cleaning cup with pure water, let it dry sufficiently, and store
it so that dust does not get inside
