8-10 Maintenance
Examine the test pattern. The example below shows a test pattern of all
nozzles functioning correctly on the color and black print cartridges.
Compare the diagonal same-color lines at the top and bottom of the test
pattern. Look for a break in the diagonal lines; a broken line shows any
clogged nozzles.
If the bottom line shows improvement, rerun this t est. If improvement
continues, rerun the test. If all nozzles are not printing after running the
test three times, continue with step 5.
