Hardware installation suggestions
Check the printer
• Make sure that all packing tape and material have been removed from outside and
inside the printer.
• Make sure that the printer is loaded with paper.
• Make sure that no lights are on or blinking except the Ready light, which should be
on. If the Attention light is blinking, check for messages on the printer control panel.
Check the hardware connections
• Make sure that any cords and cables that you are using are in good working order.
• Make sure that the power cord is connected securely to both the printer and to
a working power outlet.
Check the printheads and ink cartridges
• Make sure that all of the printheads and ink cartridges are firmly installed in their
correct, colorcoded slot. Press down firmly on each one to ensure proper contact.
The printer cannot work if they are not all installed.
• Make sure that the printhead latch is closed correctly.
• If the display shows a printhead error message, clean the contacts on the
printheads.
HP software installation suggestions
Check the computer system
• Make sure that your computer is running one of the supported operating systems.
• Make sure that the computer meets at least the minimum system requirements.
• In the Windows Device Manager, make sure that the USB drivers have not been
disabled.
• If you are using a computer running Windows, and the computer cannot detect the
printer, run the uninstallation utility (util\ccc\uninstall.bat on the installation CD) to
perform a clean uninstallation of the printer driver. Restart your computer, and
reinstall the printer driver.
