Is there an iosX driver for a cancan 4200f?
Where can I find a driver for a Canon Canoscan 4200f?
I checked Canon's website and learned that they don't provide a driver for OSX.
iTunes 11-OTHER, OS X Mountain Lion (10.8.2)
There are not drivers for iosX as that doesn't exist.
Here is the printer/scanner compatibility list for OS X, and it doesn't list that scanner.

If Canon does not provide a driver, and Image Capture doesn't recognize the scanner, i'm not sure you'll find any way to make it work as even VueScan doesn't support it on OS X.
