Scanner is also working. I don't know any GUI application for scanner but
scanimage command works fine and there is also a SANE backend which can be found at
http://home.arcor.de/wittawat/pixma/. After installation scanner is working with
pixmascan command. This is a little problematic because I couldn't scan into
tiff file format.
Only problem I have so far with
imagescan is I can't scan a multipage document.
