Sorry to say, but it looks like you're out of luck. There don't seem to be any
drivers that support that model. Even the proprietary
VueScan software doesn't cover it.
Canon is not very Linux-Friendly in general, though, so it's not surprising. I have a CanoScan 5000F myself that I haven't been able to use since I got it 4 years ago. I had to buy a new Epson scanner instead.
