Many thanks for your report.

--souce option usually resets previous settings.

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



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).

Please have a look at this table:

Hope this helps.
