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: • Clean the printhead • Calibrate the linefeed • Align the printhead • 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 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 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. 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 the printer off. To clean the printhead from the control panel 1. Load Letter, A4, or Legal unused plain white paper into the main input tray. 2. Touch (right arrow), and then select Setup. 3. Touch Tools, and then select Clean Printhead. To clean the printhead from Toolbox (Windows) 1. Open Toolbox. For more information, see Open the Toolbox. 2. From the Device Services tab, click the icon to the left of Clean Printheads. 3. Follow the on-screen instructions. Printhead maintenance 151
