There are two approaches I can think of off the cuff. One possibility is
that there 'may' be a way to control the light programatically. That
would mean writing your own control software, and you'd need to
get hold of a description of the interface protocol between the computer
and the scanner. Probably not a simple task. Some URL's to check out
would be <http://panda.mostang.com/sane/> and
<http://www.twain.org/>. Those are higher level software interfaces that
might give you something you could use.
The second, and simpler, possibility would be to open the scanner case,
and install a switch in the power supply leads to the lamp. Then you
could manually interrupt the power. Don't know if the scanner would notice
this or not? If there is any kind of automatic gain control it might go
to its maximum gain setting. Also don't know if there is any kind of
calibration of the lamp before each scan. If so, that could cause some
problems.
