Chapter 8 Clean the printhead If your printed output is streaked, the printhead might need to be cleaned. 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 three stages of cleaning, try aligning the printhead. If print quality problems persist after cleaning and aligning, contact HP support. For more information, see HP support. 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 Load paper. Not turning the printer off correctly can cause print quality problems. For more information, see Turn off the printer. To clean the printhead from Toolbox (Windows) 1.
