I have observed this problem as well, using 13.04 x86_64, 3.6.1-0ubuntu1. My scanner is a HP Photosmart Premium c309a, connected via the network.
When scanning multiple pages, the scanner will not eject the last page and waits for additional pages to be fed. It seems it's not able to detect that there are no more pages in the feeder.
