Check the ink cartridges
Make sure that all of the ink cartridges are firmly installed and aligned in their correct,
color-coded slot. A correctly installed ink cartridge should not move when pulled
slightly. The printer cannot work if all the ink cartridges are not installed.

reinstall the printer driver.
Verify installation preliminaries
• Make sure to use the installation CD that contains the correct HP software for your
operating system.
