To align the printheads

Whenever you replace a printhead, the device automatically aligns the printheads to ensure the best print quality. However, if the appearance of your printed pages indicates that the printheads are misaligned, you can start the alignment process manually.

•Control panel: Press the Setup button, select Tools, select Align Printer, and then press OK. Press OK when the alignment is done to continue.

•Embedded Web server: Click the Settings tab, click Device Services in the left pane, select Align Printheads from the drop-down list in the Print Quality section, and then click Run Diagnostic.

•Toolbox (Windows): Click the Services tab, and then click Align Printheads and follow the onscreen instructions.

•HP Printer Utility (Mac OS): Click Align from the Information and Support panel.
