Printhead maintenance

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.

Performing the aligning and cleaning procedures unnecessarily can waste ink and shorten the life of

the cartridges.

This section contains the following topics:

●

Calibrate the linefeed

●

Reinstall the printhead

Clean the printhead

If your printed output is streaked or has any incorrect or missing colors, the printhead might need to

be cleaned.

There are two 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 both 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

on page

122.

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. Before cleaning the printhead, make

sure you load paper. For more information, see
