The printer feeds a sheet of paper and prints a nozzle test pattern,
similar to the one shown:
3
Examine the test pattern.
4
Compare the diagonal lines above the printed bars to the diagonal lines
below the printed bars.
Look for breaks in the diagonal lines above the printed bars. Broken
lines indicate clogged nozzles.
•
If the bottom line still has breaks, 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, go to step 5.
5
Remove and reinstall the print cartridge.
6
Repeat the nozzle test.
7
If the lines are still broken, wipe the print cartridge nozzles. For help,
see “Wiping print nozzles and contacts” on page 37.
