HP Photosmart D7460 Printer - Manual (Page 169)

Cause: The wrong ink cartridge(s) are installed.
Solution: The first time you set up and use the HP Photosmart, make sure to install
the ink cartridges that were shipped with your device. The ink in these ink cartridges
is specially formulated to mix with the ink in the print head assembly.
To resolve this error, replace the affected ink cartridge(s) with the ink cartridges that
were shipped with the HP Photosmart.
