HP scanjet 8200 inop after Leopard to Snow Leopard upgrade
I upgraded my 2008 iMac Intel computer to Snow Leopard from Leopard, and then did the download process to end up at 10.6.8. After this I found that my HP 8200 flatbed scanner wasn't recognized by the iMac. Searched for HP software upgrade to work with Snow Leopard 10.6.8 and downloaded that from the HP site. Even though the first portion of that download was successful, upon reboot to finish the install the computer doesn't follow up with the finishing steps. Tried the HP download twice with the same result.
The scanner is still unusable, and when I try to uninstall the HP scanner it can't be done because the files are corrupted and unavailable. Used the Time Machine to go back prior to the Snow Leopard upgrade, but the scanner is still unrecognized. Would the proper procedure for this have been to uninstall the scanner prior to the OS upgrade to Snow Leopard, and then reinstall the scanner, followed by downloading the drivers needed for Snow Leopard? Or is there some inherent conflict with the drivers on the 8200 install disc that will corrupt the process if Snow Leopard is the OS when I do the install? How do I proceed from here to make the scanner functional with Snow Leopard?
