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.

Lines missing here indicate the printhead requires cleaning.

Unevenness in these patterns indicates the printhead requires alignment.
