SUMMARY If the ADF is empty and the user still asks for a scan to be performed, a reasonable assumption would be that the user has put a document on the flatbed, so Skanpage should fall back to just scanning from the flatbed. STEPS TO REPRODUCE 1. Put nothing in the document feeder. 2. Ask Skanpage to scan from the ADF. OBSERVED RESULT A dialogue box appears telling me there is nothing in the ADF. EXPECTED RESULT Skanpage scans from the flatbed instead (or, alternatively, asks me if I want to do so).
