Thanks for pointing that out: I cloned the git repos yesterday: git clone git://git.debian.org/sane/sane-backends.git and did a default build. Now I am able to scan: $ scanimage -L device `pixma:MX520_F934C5000000' is a CANON Canon PIXMA MX520 Series multi-function peripheral device `pixma:04A91769_12999B' is a CANON Canon PIXMA MX520 Series multi-function peripheral $ scanimage>/tmp/img $ It also works without the usb cable connected: $ scanimage -L device `pixma:MX520_F934C5000000' is a CANON Canon PIXMA MX520 Series multi-function peripheral $ scanimage>/tmp/img $ > I also find the scangearmp a little bit bad, I'm not excited from ...

I see similar behaviour: $ scanadf -v --source 'Automatic Document Feeder' scanadf: scanning image of size 638x877 pixels at 24 bits/pixel scanadf: acquiring RGB frame scanadf: min/max graylevel value = 31/255 Scanned document image-0001 scanadf: scanning image of size 638x877 pixels at 24 bits/pixel scanadf: acquiring RGB frame scanadf: min/max graylevel value = 40/255 Scanned document image-0002 scanadf: scanning image of size 638x877 pixels at 24 bits/pixel scanadf: acquiring RGB frame scanadf: min/max graylevel value = 38/255 Scanned document image-0003 scanadf: scanning image of size 638x877 pixels at 24 bits/pixel scanadf: acquiring RGB frame scanadf: min/max graylevel value = 40/255 Scanned document image-0004 scanadf: scanning image of size 638x877 pixels at 24 bits/pixel scanadf: acquiring RGB frame scanadf: min/max graylevel value = 46/255 Scanned document image-0005 scanadf: scanning image of size 638x877 pixels at 24 bits/pixel scanadf: acquiring RGB frame [bjnp] bjnp_recv_header: ERROR - could not read response header (select timed out)!
