This printer has a self-cleaning function and

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:
(1) Just after ink charging
(2) After head cleaning
(3) When printing starts
Also, number (3) is performed using ON:
PERIODICALLY or ON: EVERY JOB, depending on
the timing selected on the control panel. When
clogging is detected, auto cleaning is performed
the number of times set on the control panel (the
factory setting is once; three times maximum)
until the clogged nozzles are cleared; number (2)
is only performed once regardless of the preset
number.

Maintenance
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.
