This is not quite clear to me. If you don't want to use the ADF-unit but  
just want to scan in flatbed mode you will need no further arguments.
If you try to scan in ADF mode and there are no sheets in the ADF-unit,  
scanadf/scanimage simply will exit with a "scanned 0 pages".
A simple command line call could look like this: scanadf --source  
Automatic Document Feeder --speed=yes -o ~/scanadf/image-%d. If you want  
speed you must take care that the speed option is activated (really makes  
a difference).

If ADF isn't essential for you you might have a look on the Avasys website  
(is Epson actually). There is a list of supported scanners (flatbed too).  
They have Sane compatibility.
In my experience Epson scanners are pretty fast.Sadly,the fastest,the  
Perfection 1670, isn't available anymore.
