This video shows how to print a self-test page on the HP Officejet Pro L7780 All-in-One printer. A self-test page can help identify the source of a printing problem. If you can print a self-test page and the self-test page looks ‘normal’, then you know the source of the printing problem is somewhere else. The steps shown in this video are the same for the Officejet L7650, L7680, and L7750. I am an HP employee but I do not represent HP on this site.
