Mike- Chances are that your machine does not support ADF Backside. Many of the older machines don't. However, it certainly should support duplex. Can you get a log like so:
SANE_DEBUG_FUJITSU=35 scanimage --resolution 50 --source "ADF Duplex" -b 2>4097.log That should produce out1.pnm, out2.pnm, and 4097.log in the current directory. Send me the log (compressed if it is big). I should be able to pinpoint the problem pretty quickly. allan
