Using print cartridges
This example shows a test pattern of a colour nozzle functioning
correctly.
Compare the diagonal line above the printed bars 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.
If the print quality of both lines is not satisfactory after running the test
three times, continue with the following steps.

key, press 1 for OLD BLACK CART or 2 for OLD COLOUR
CART on the Sharp Colour MFP.
