non standard. oliver and i both have the interface manual, what we dont 
have is time :)

i have been experimenting with double feed and paper jam detection on the 
4120 the past few days, and so have been looking at the manual in that 
area. it seems that the paperlength detection revolves around the scanner 
throwing an error when thedocument is smaller than the window length or 
defined paper length, and the driver catching the error. That does not 
seem all that useful, but perhaps i am missing something. the docs are 
poorly translated from japanese.

you want a copy?
