Cleaning the printheads
The printheads for your all-in-one have microscopic nozzles. The all-in-one is designed to
prevent nozzles from drying out when the all-in-one is idle and when it is turned off.
Clean the printheads for the following reasons:
z
When the printhead nozzles become clogged. Nozzles can become clogged when
exposed to the air for more than a few minutes. A printhead that is not used for long
periods of time can also clog, resulting in a noticeable degradation of print quality.
z
When lines or dots are missing from printed text or graphics.
Cleaning the printheads takes several minutes. When the process is complete, the all-in-one
prints two pages that contain cleaning patterns.
Note
Clean the printheads only when necessary. Cleaning the printheads when defects do not occur
in printed text or graphics wastes ink and shortens the life of the printheads.
