Cleaning the print cartridges
This section contains a procedure for cleaning the print cartridges automatically. For information
about cleaning the cartridges manually, see
The printer is rejecting the pen .
To clean the print cartridges automatically
The print cartridges have microscopic nozzles that can clog when exposed to air for too long. In
addition, if a print cartridge is not used for long periods of time it can also clog, resulting in a
noticeable decrease in print quality. Cleaning the print cartridges unclogs the nozzles.
Clean the print cartridges if the printed characters are incomplete, or if dots or lines are missing from
the printed text or graphics.
NOTE Cleaning the print cartridges when it is not necessary wastes ink and reduces the life
of the print cartridges.
If print quality has degraded, it could be that the cartridge is out of ink. Check the ink level
before proceeding to clean the cartridges. If the cartridge is out of ink, replace it.
