Keeping the Best Printing Results
To avoid drying of the Print Head and clogging of the nozzles, note the following.
• When You Turn Off the Machine
Follow the procedure below to turn off the machine.
(1) Press the ON/OFF button to turn off the machine.
(2) Confirm that the POWER lamp has gone out.
This takes a few seconds or as long as around 30 seconds.
(3) Unplug the power cord from the wall outlet.
If you are using a power outlet strip, you can switch it off instead.
When you press the ON/OFF button
to turn off the machine, the machine automatically puts a
protective cap on the Print Head to prevent the ink from drying. If you remove the power cord or
switch off the power outlet strip before the POWER lamp goes out, this capping will not be done
properly, causing the Print Head to dry and clog.
• When You Are Not Using the Machine for a Long Time
When you are not using the machine for a long time, print or copy in both black & white and in
color, or perform Print Head Cleaning, about once a month to prevent degradation of the Print
Head.
Numerous nozzles are installed
in the Print Head for high-precision printing. Just as the
uncapped tip
of a ballpoint pen or marker becomes dry and unusable if it is not used for a long
period
of time, the print head nozzles become blocked by dried ink. Periodically printing or
cleaning the Print Head can prevent this blockage.
~ Note
• If the printed area is traced with a highlight pen or paint-stick or stained with water or sweat, ink
may blur depending
on the paper.
• If the print head nozzles get clogged, printouts will become faint or particular colors will not be
printed properly. For details, see "When Printing Becomes Faint or Colors Are Incorrect"
on
page 56.
