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
device, run the uninstallation utility (util\ccc\uninstall.bat on the Starter CD) to
perform a clean uninstallation of the device driver. Restart your computer, and
reinstall the device driver.
Verify installation preliminaries

Starter CD for damage. You can download the device driver from the HP Web site
(
