When Not Using for a Long Period of Time
If the machine will not be used for a long time, turn its power off, disconnect the USB cable, and then
unplug it from the wall outlet. It is recommended to print at least once a month, because the machine
consumes a considerable amount of ink for periodic maintenance and print head cleaning when turned
on after a long period of inactivity.
• If this machine is not going to be used for several days or longer at a time, disconnect its power
cord from the wall outlet.
• When disconnecting the power cord from the wall outlet, always pull the plug, not the cord.
Pulling the cord can damage the power cord. Use of damaged power cords could result in fire
or electric shock.
Be careful of the following:
• The nozzles of the print heads may dry out and become clogged. To prevent this, periodically print
something. Even if you do not print anything, turn the machine on for a few minutes once every
20-25 days.
• If you do not use the machine for a long period of time, always check if the nozzles are clogged by
printing a nozzle check test pattern. See page 131 "Nozzle Check". Clean the print heads as
necessary, and then begin printing. See page 132 "Head-cleaning".
• If you try to use the machine after it has been out of use for a long time, it may not print properly
even if head cleaning is carried out several times. If this is the case, carry out head flushing. See
page 134 "Head-flushing". If the print heads are still clogged, leave the machine for about ten
minutes, and then print the nozzle check pattern. If the problem persists, turn the machine off and
leave it for at least eight hours. This should unclog the print heads.
• After head cleaning is performed multiple times, clogged ink will dissolve over time, and normal
printing may become possible.
• If there is no improvement after performing the steps above, contact sales or service representative.
