You need to reorder the options of scanimage.

'scanimage --help' tells me:
Usage: scanimage [OPTION]...
    --source Flatbed|Transparency Unit [Flatbed]
        Selects the scan source (such as a document-feeder). Set source
        mode and resolution. Resets mode and resolution to auto values.

My scanner has a transparent unit and no document feeder, but the
handling is the same.

$ scanimage --source "Automatic Document Feeder" --resolution 300
should work.
