Automatic maintenance
function
This printer has a self-cleaning function and
capping function for maintaining the print head
in consistently good condition to ensure the best
print quality.
AUTO NOZZLE CHECK function
The printer performs a nozzle check without
printing a pattern, and if there are missing dots, it
performs cleaning automatically (taking 2 to 13
minutes).
The AUTO NOZZLE CHECK function works in the
following cases:
❏ When the power is on.
❏ After head cleaning and ink charging.
❏ Before changing the black ink type.
❏ When printing is started.
However, to maintain the print quality, the AUTO
NOZZLE CHECK function works after head cleaning,
ink charging, and changing the black ink type
even if the AUTO NOZZLE CHECK function is off.
Self-cleaning function
Self-cleaning is a function for cleaning the print
head automatically to prevent the nozzles getting
clogged. It is performed periodically, for example
when you turn the printer on (during warming
up). A minute quantity of ink is drawn from each
ink cartridge to prevent the nozzle drying out.
Even if you press the
self-cleaning, the power is not turned off until
cleaning finishes. Do not pull out the power plug
of the printer during cleaning.
The self-cleaning function is not available when
AUTO NOZZLE CHECK is OFF.

Capping function
Capping is a function for automatically covering
the print head with a cap (lid) to prevent the print
head from drying out. Capping is performed in
the following situations.
❏ When several seconds have elapsed after
printing finishes (that is there is no print data
sent)
❏ When printing is stopped
Take care of the following points to ensure that
the print head is capped properly.
❏ If the print head is not positioned on the right
side (it is not capped), turn the printer on,
then off again. By turning the printer off with
the button, the head is capped properly.
❏ If you turn the power off when a paper jam or
error occurs and the print head is not capped,
turn the printer on again. Shortly, the print
head is capped automatically. Check that it is
properly capped, then turn the printer off.
❏ Do not move the print head manually under
any circumstances.
❏ Do not remove the power plug of the printer
when the power is on, or cut the power at the
breaker. The head may not be capped
properly.
