Canon CanoScan 8000F Scanner : Mac OSX 10.5.7 : Photoshop CS4.

I can not seem to locate a driver that works in the above environment. To scan from the Canon into Photoshop.
ScanGear CS 8.1X seems to be the latest version, but does not work. I take it you would download the latest Driver install in Adobe Photoshop > Import-Export folder, then restart computer. Has anyone any suggestions, or do I buy a new scanner?
