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. 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. To clean or align the printheads 1.
