There is an option 'sleeptimer'. I think it's the time in minutes(?) until the
lamp is turned off. I've not tried it with the 4120.

I don't know about the 4120, but the big brothers of that scanner are able to 
do a paper length detection. It works fine with TWAIN but I've not 
implemented it in SANE, yet.
