NukeShim,
Could confirm that you're seeing the scanner, that is the LiDE-80 specifcally, under Image Capture in Mavericks, and that you can scan? Not showing up for me on a 2012 MBP running the latest 10.8.5 .
I'd actually really be surprised if it would, since the LiDe-80 specifically was internally different from the rest of the LiDE series. Canon didn't write the original drivers for them, some 3d-party did. The drivers were weak MacOS 9 updates (filename limited to 32 chars, no unicode support). They were never updated for the Intel Macs, unlike most of the LiDE line. I know this because I corresponded with Canon on this in 2008. The last driver is a PowerPC one from 2005, which officially supports up to 10.4 only, although IIRC it did work for me on 10.5 for a while after doing some manual installing.
