I've been desperately trying to make that work for the past weeks.
My scanner requires Sane backend version 1.0.23 (Canon i-Sensys MF4430).
I've checked on the Sane Project website and they confirmed that only the latest version supports my scanner.
So, I've installed the latest version from git (and made it from the source), and then scanimage -V returns:
scanimage (sane-backends) 1.0.23; backend version 1.0.23
And it's OK.
But when I install XSane or Simple-Scan, scanimage -V returns:
scanimage (sane-backends) 1.0.23; backend version 1.0.22
I've tried to add symbolic links as specified in the ReadMe but It's always pointing to the former Sane version (probably the one installed by my Linux Mint 13 distribution)...
Please can someone help me?
