Cleaning the Printhead

Cleaning the Printhead
If the nozzles become blocked, cleaning the printhead may
recover optimum printer operation.
Note
When you set Nozzle Check, the printer performs a
nozzle check and recovery automatically for every
page specified for printing. Before shipping a printer,
the setting is set for 10 Pages.

Types of Printhead Cleaning

There are two methods for printhead cleaning.
Head Cleaning A:
Execute when printing appears uneven, or when the
printhead is dirty. This cleaning method consumes the
least amount of ink. Head Cleaning A requires about 1
minute.
Head Cleaning B:
Perform this cleaning if no ink is coming out of the print-
head or if Head Cleaning A did not correct the problem.
Head Cleaning B requires about 3 minutes.

Printhead Cleaning Procedures

Follow this procedure to clean the printhead. The procedure
is almost the same for each cleaning method.
If one execution of Head Cleaning A does not correct the
problem, perform 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
performing Head Cleaning B, the printhead may be at the
end of its service life. Call for service or contact the dealer
where you purchased the printer. (→ P.4-23)
Note
You can execute Head Cleaning A by holding down
the Information button for more than three seconds.
