Public bug reported: The scanner only does the first operation after I plug it in. E.g. preview a page, or scan it. On the second operation, the mechanical part does not move anymore (there is no noise whatsoever from the scanner), and the scan output is pitch black.
The workaround I have found is to run scanimage -L between each operation. I.e.: - Start Xsane - Preview - run scanimage -L - Scan - run scanimage -L - Preview - run scanimage -L - Scan ...
