Maintain the printhead and ink cartridges

If you are experiencing problems with printing, you might have a problem with the printhead. You

should perform the procedures in the following sections only when directed to do so for resolving print

quality issues. For more information, see Print quality report.
Performing the aligning and cleaning procedures unnecessarily can waste ink and shorten the life of

the cartridges.

Clean the printhead if your printed output is streaked or has any incorrect or missing colors.
There are three stages of cleaning. Each stage lasts about two minutes, uses one sheet of

paper, and uses an increasing amount of ink. After each stage, review the quality of the printed

page. You should only initiate the next phase of cleaning if the print quality is poor.
If print quality still seems poor after you complete all stages of cleaning, try aligning the printer. If

print quality problems persist after cleaning and aligning, contact HP support. For more

information, see HP support.

Align the printer when the printer status page shows streaking or white lines through any of the

blocks of color, or if you are having print quality issues with your printouts.
The printer automatically aligns the printhead during the initial setup.

Clean ink smears when your printed output has smearing on the back. Ink may have built up in

some areas of the printer and needs to be removed.

NOTE: Cleaning uses ink, so clean the printhead only when necessary. The cleaning process takes

a few minutes. Some noise might be generated in the process.
Turning the printer off improperly can cause print quality problems. For more information, see Turn

the printer off.

From the printer control panel display, touch Setup.
