IMPORANT INFORMATION
•This machine is a precision device. Never subject the machine to impacts or excessive force.
•Never needlessly put your hand or fingers inside the cover, the ink-pouch ports, or other
internal areas of the machine. The print heads are delicate.
•Never needlessly touch or allow media to scrape them. The print heads may be damaged if
allowed to dry out. The machine prevents desiccation automatically, but improper operation
may render this feature inoperative.
•Never leave the machine with an ink pouch removed. Remaining ink in the printer may harden
and clog the print heads. Depending on the situation, the print heads require various types of
cleaning. The print heads are components that wear out. Periodic replacement may be
required, with the frequency of replacement depending on use.
•This machine becomes hot. Never cover the ventilation holes with cloth, tape, or anything
else.
EMPTY THE DRAIN BOTTLE
•To prevent waste ink overflowing, please empty the waste ink bottle.
•The machine will perform automatic cleaning and will purge a small amount of ink into the
