Replacing the Ink Cartridges and Printheads on the HP Officejet Pro L7780 All-in-One Printer

This video explains how to replace the ink cartridges and printheads on an HP Officejet Pro L7780 All-in-One Printer. The steps shown here are the same for the Officjet L7650, L7680, and L7750. I am an HP employee but I do not represent HP on this site.

    Why does it have an extra paper tray?

    The L7780 was shipped with a 2nd paper tray. It is an optional accessory on the rest of the L7xxx series.
