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 50.

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

takes a few minutes. Some noise might be generated in the process. Before cleaning the printheads,

make sure you load paper. For more information, see Load paper on page 11.

Not turning the printer off correctly can cause print quality problems. For more information, see Turn

the printer off on page 14.
