4. When the printer is not used for a long period
When the printer is not to be used for a period of one week or above, perform the cleaning of the heads and
nozzles and the ink discharging channel before storing this printer.
When cleaning, be sure to provide adequate ventilation and be sure to wear the supplied protective
glasses and gloves.
When ink is mixed with water or alcohol, aggregates are generated. Do not to allow water or alcohol to
deposit to the nozzle surface, around the head, cap, and wiper.
To ensure ink ejection stability, this machine must periodically eject (flush) a small amount of ink
depending on the ink type when it is not used (output) for a long time.
When not using this machine for an extended period of time, execute the [CUSTODY WASH] function,
("When the Machine Is Not Used for a Long Time (CUSTODY WASH)" Chapter 4 of Operation Man-
ual) and turn off only the power button on the front panel. The main power switch on the right side
should be on (in the state of |) and the outlet should be inserted.
