When Not in Use for a Prolonged Period

Keep Performing Maintenance

Switch on the power once a month
Switch on the sub power once a month. When you turn on the power, the machine automatically performs
operations such as those to keep the print heads from drying out. Leaving the machine unused for a prolonged
period may damage the print heads, so be sure to switch on the power to perform these automatic operations.
Keep at a constant temperature and relative humidity
Even when the machine is not in use, keep it at a temperature of 5 to 40°C (41 to 104°F) and a relative humidity
of 20 to 80% (with no condensation). Temperatures that are too high may degrade the ink and cause malfunc-
tion. Temperatures that are too low may cause the ink to freeze and damage the heads.

PRESS THE POWER
KEY TO CLEAN
The alarm feature reminds you to switch on the sub power once a month. When the machine remains unused
for about one month, this screen appears and a warning beep sounds. If this screen appears, switch on the
sub power. When maintenance operations finish, switch off the sub power.
This feature operates when the printer's main power is turned on. Leave the main power switched on at all
times even when the printer is to remain out of use for a prolonged period.

If the Machine Has Not Been Used for One Month or More

If the machine has not been used for one month or more, refresh the subtanks. If you use the machine straight
away without performing this procedure, printing may be adversely affected, e.g. printed colors may be
unstable.
