When I scan multiple page documents using the ADF, all pages are feeded, but only page 1 shows in XSANE.
For XSANE 0.98 or earlier :
You will have to modify the multipage scanning option in XSANE.
In XSANE, click on Preferences, Setup, Enhancements. Change the "Automatic document Feeder Modus:" from "None" to " Automatic Document Feeder".
For XSANE 0.99 or later :
You will have to indicate the number of pages. Please increase the number in the box at the top left corner on the XSANE main window.
