Compare the diagonal line at the top and bottom of the test pattern.
Look for a break in the diagonal line. A broken line shows any
clogged nozzles.
If the bottom line shows improvement, rerun this test. If
improvement continues, rerun the test again. If all nozzles are not
printing after running the test three times, continue with the next
step.

If print quality does not improve, remove and reinstall the print
cartridge. See ÔReplacing the Print CartridgeÕ on page 7.10 for
complete instructions on removing and reinstalling a print
cartridge.

If the line is still broken, wipe the nozzles and contacts. For help,
