Maintaining the printheads
Cleaning the printheads
The printheads for your printer have microscopic nozzles that can clog
when exposed to the air for more than a few minutes. The printer is
designed to prevent nozzles from drying out when the printer is idle and
when it is turned off by pressing and holding down
(power button)
on the printer.
A printhead that is not used for long periods of time can also clog,
resulting in a noticeable decrease in print quality. To unclog the
nozzles, clean the printheads.
Clean the printheads when lines or dots are missing from printed text or
graphics. These defects occur when ink nozzles in the printheads are
exposed to air for long periods of time.
Note Cleaning the printheads when defects do not occur in printed text
or graphics wastes ink and shortens the life of the printheads.
