Please try this: $ scanadf -d pixma:04A91855_103CD1 --source "Automatic Document Feeder" --mode Lineart --output-file foo%02d.pbm For testing ADF I prefer to use gscan2pdf and for "normal" scans xsane. You can see some logs with: $ SANE_DEBUG_PIXMA=11 gscan2pdf or $ SANE_DEBUG_PIXMA=11 xsane add this if you want to save the log into a file: &> pixma.log You can decrease the log level to reduce log depth (see 'man sane-pixma' for details). <snip> > In the case of it being possible to return this device and get something > else in its place, which manufacturer/model would be preferred to have > *full* functionality with Free Software only? Any recommendations? Please have a look at this table: http://www.sane-project.org/sane-backends.html Hope this helps. Cheers, Rolf
