In that case, you will need to install some generic (FREE) TWAIN-drivers : …some for some printers, like the Canon CanoScan LiDE 20 and LiDE 30, the TWAIN-drivers are not included in OSX. – then it will be listed in the previous (“Print & Scan”) System Preferences window, and if you select it (and you put a piece of paper or a photo in the scanner), a Scanning Preview window will show up, allowing you to scan your document to file or eMail or something else…

– if your scanner is TWAIN-supporting, it will show up there, and you just need to select it and click on the “Add”-button – that will bring up the “Add”-window, which enables you to add a new printer or scanner – then, just below in the list of printers on the left, click on the “+”-sign – connect your scanner directly to your Mac using a USB-cable In OSX 10.7 Lion and 10.8 Mountain Lion any TWAIN-supporting scanner can be used without any additional software : But now I’ve bought a new Mac which runs OSX 10.8 Mountain Lion, I can’t seem to install it, since Canon doesn’t update the drivers anymore. I have a Canon CanoScan LiDE 20 that used to work perfectly in MacOSX 10.6 Snow Leopard. UPDATE : Mattias Ellert has now updated the TWAIN SANE drivers, so there is a new version for OSX 10.9 Mavericks (and OSX 10.8 Mountain Lion), more on this can be found here UPDATE : a list of supported scanners for OSX 10.9 Mavericks can be found here
