I think that this issue has nothing to do with (X)SANE. I own a ScanJet 8250 
and encountered this problem recently. It appeared to be related to one of 
the detectors not working properly. When I followed the advice in:
the problem was resolved.

There is another annoying problem with the Avision backend (I think but am not 
sure) that remains: it will not allow to use the duplex facility of the 
ScanJet 8250. When you put the switch on the scanner to duplex scanning, it 
will continue to scan only one side. It works perfectly well when using the 
HP software under Windows though... This problem has been reported before, 

Regards, Paul.
