Cleaning the ink cartridge nozzles

To improve print quality, you may need to clean the ink cartridge nozzles.

Clean the nozzles when:

• Characters are not printing completely.
• White dashes appear in graphics or printed text.
• Print is smudged or too dark.
• Colors on print jobs are faded or they differ from the colors on the screen.
• Vertical, straight lines are not smooth.

You can use the operator panel or the Dell Printer Solution Center to clean the 
nozzles.

A nozzle page prints, forcing ink through the nozzles to clean the clogged 
nozzles.

• Print your document again to verify your print quality has improved.
• To further improve print quality, try wiping the ink cartridge nozzles 

and contacts (refer to your User’s Guide), and then print your 

document again.

• If print quality has not improved, try cleaning the ink cartridge nozzles 

up to two more times.
