Okay - this setup might be a problem indeed, since there is no automatic  
switch back to flatbed mode as soon one is working with the ADF mode.

Maybe there did someone a 9600 dpi scan :) . Maybe the tests were done  
under windows (which clearly was slower than the Sane driver). Anyway, in  
my normal use with 300 dpi scans of A4 pages I haven't seen a faster  
scanner till now. And with some photo scans I never got something similar  
like 56 s. However this scanner is out of market since a couple of years,  
so it won't be an option.
