There are approximately 200 nozzles on each of the
cartridges. Depending on the cartridge type, the nozzles
are all one color (black) or split into 3 groups of different
colors (color or photo).
Cleaning the ink jet nozzles on the print cartridges
improves the print quality.
There are several situations that can result in some of the
nozzles not working properly.
xý If the cartridge is new, it may take a couple of
cleaning cycles to get all of the nozzles working.
xý If the printer has not been used for an extended
period of time, the cartridges may not function
properly.
xý A build up of ink on the bottom of the cartridge
may affect the cartridge performance.
xý If the cartridge is running out of ink, the cartridge
will not function properly. In this case, cleaning
the cartridge will not help the nozzles to fire. You
must replace the ink cartridge.
There are two methods to clean the ink cartridges:

to the diagonal line below the printed bars.
Look for a break in the diagonal lines. A broken line
indicates clogged nozzles.
If the bottom line has fewer breaks, or better print
quality than the top line, run the test two more times. If
the print quality is satisfactory after running the test
three times, the print nozzles are clean. You do not
need to complete the remaining steps.
If the print quality of both lines is not satisfactory after
running the test three times, perform the following
steps.
a.ý Remove and reinstall the print cartridge. For
more information see the Changing Print
Cartridges section.
