Cleaning the Printhead

Cleaning the Printhead
When the ink nozzles of the printhead become clogged,
you can restore normal operation by cleaning the printhead.
Note
If you activate the Nozzle Check setting, the printer
checks the nozzles and executes automatic recovery
each time the specified number of pages are printed.
The default setting is 10 Pages.

Types of Printhead Cleaning

There are two methods for printhead cleaning.
Head Cleaning A:
Execute Head Cleaning A when printing appears
uneven, or when the printhead is dirty. This cleaning
method consumes the least amount of ink. Head
Cleaning A requires approximately 90 seconds.
Head Cleaning B:
Execute Head Cleaning B if no ink is coming out of the
printhead or if Head Cleaning A did not correct the
problem. Head Cleaning B requires approximately 3
mins. 30 seconds.

Printhead Cleaning Procedure

Follow this procedure to clean the printhead. The procedure
is almost the same for each method.
If printing does not improve after executing Head Cleaning
A once, execute Head Cleaning B. If Head Cleaning B does
not correct the problem, repeat Head Cleaning B two or
three times. If the printer operation does not recover after
running Cleaning B, the printhead may have reached the
end of its service life. Call for service or contact the dealer
where you purchased the printer.
Note
You can execute Head Cleaning A by holding down
the Information button for more than three seconds.
