Printing a Nozzle Check Pattern

The printhead discharges ink through nozzles—tiny openings from which the ink
is sprayed. If faded or streaked colors and text appear on your output when you
print, some of the nozzles may be clogged. You can check for this problem by
printing a nozzle check pattern.
The nozzle check pattern should appear as follows when ink is discharged
properly. Examine the nozzle check pattern output.
