Newbie question setting up a Canon imageclass mf4570dn printer and scanner. I have set up the canon drivers and printing works fine.
However, I can not get the scanner to work. I installed un-released sane version per the instructions in http://ubuntuforums.org/showthread.php?t=1427330
but when I get to the terminal comman scanimage -L - the scanner is not recognized. Actually, it can't connect to a gnome key ring, then the scanner is not recognized. If I use sudo scanimage -L the output is just that no scanner is found.
Has anyone any ideas?
