If I turn on the batch scanning option, it is no problem having less
pages in the scanner than requested in "number of pages". It simply
scans the pages which are available and then pops up a message window
telling how many pages were actually scanned.
With batch scanning of the crash of the scanner after scanning the last
available page occurs. In this case the scan job should also
end/continue gracefully, for example asking the user to insert more pages.
