[sane-devel] Canon mf3110 and CanoScan 4400f

[Aleksandr Charkov]

I don't know how exactly sane works, so I did this:

downloaded git sane-backends, compiled it, installed with 'make install'
and ran it '/usr/local/bin/scanimage -T   2> mf3110.log'
Am I did right?

Also, between this two messages: 'reading one scanline, 1920 bytes...' 
and 'Error during device I/O';
scanner end to scan and waiting about 2 minutes.
