After 2 days online w/Canon Tech & them telling me this was not a printer problem but an Windows XP problem I have yet to resolve this issue. My printer all of a sudden quit communicating w/my cpu. So on instruction from Canon I attempted to uninstall & reinstall w/o success. I keep getting CRC errors on four files remaining in the Canon directory. I cannot even do a forced install. It will not let me delete an icon on my desktop either. I'm lost & very frustrated. The hdd I have is fairly new. Less than one year. Help! Help!
