Checking for Clogged Print Head Nozzles

To maintain optimum print quality, perform a nozzle check before printing. This lets you visually inspect the printed check pattern and clean the nozzles, if necessary. There are two ways to check the nozzles:

Set up the product to automatically print a check pattern before each print job. You can select how often the product performs a nozzle check in the Printer Setup menu.
Manually run a nozzle check from the product control panel, as described here.

Press the maintenance button. You see the Maintenance menu on the product LCD screen.
Select Nozzle Check, select the print position for the check pattern, and press the OK button. The product prints a nozzle check pattern.
Check the printed pattern to see if there are gaps in the lines.
Nozzles are clean

Nozzles need cleaning
If there are no gaps, the print head is clean and you can continue printing.
If there are gaps or the pattern is faint, clean the print head.
