I tried doing a clean install, but XP will not allow original software to install. The patches (there are two releases: 654 & 700)are just that...patches that have to installed on top of the original software. HP recommends using Win95, 98, ME to install the original scanner software, upgrading to XP, and installing the XP patch(es). Which I did and it worked fine for a while. At some point it stopped working. Now, when I try to access it, I get a faliure to communicate error. All the software is still intact.
