Take a look at 

http://www.remote.org/frederik/projects/software/sane/

It's a program that "watches" for the scanner buttons to be pressed and
launches a user defined program (e.g. scanimage or scanadf) when that 
happens.  This particular program is specific to Fujitsu scanners and uses 
the SCSI "sense" command to poll the scanner and detect when the 
button is pressed.

I wanted to do something similar with my Microtek PageWiz which can detect
when a sheet of paper is in the feeder.  I wanted it watch for that
and automatically start scanning, so I used sensed as a starting 
point for my own utility which periodically polls the scanner using
the SCSI "inquiry" command.
