How do I align or clean the printheads on the HP Smart Tank 7600?

You can align or clean the printheads from the printer control panel, from the embedded web server (EWS), or from the HP printer software on Windows. To determine if cleaning or aligning is needed, print a Print Quality Diagnostic Report by going to Menu, scrolling to Tools, touching Troubleshooting, then touching Print Quality. After reviewing the diagnostics page, follow the recommended steps to align or clean the printheads to improve print quality. (Page 82-83)
