gimlet,
I've been trying for a little while now to get the scanner to work with no luck. I noticed a couple of the gump sizes were wrong, so I updated them. But still a no go. It scans the first page just fine, turns the page, then it hangs up.
I've tried both the old kalocr file that came with the download originally as well as the most current one. Neither seem to have any affect.
Not sure what else I can try to correct the hang up, but figured I'd let you know it wasn't going to be plug-n-play if you haven't had a chance to try it yet.

Oh.. just realized that I was trying books that are in vendors. Off to try out of my pack...
No luck. Stepped through it at the point that it hangs for me, I'm not seeing what could be causing it.
