actually, it is entirely the scanners fault, i quote from the beautifully 
translated interface manual for the 4097

"If the length that is not within the physical length is specified, the 
data is padded with dummy data white for the number of bytest exceeding 
the physical length before it is transferred."

so you asked for 23 inches, you get 23.

from looking at the manual and the code (briefly), i think the backend 
gives the options for length detection, but does not actually implement 
the code needed to use it. can you give more debugging error info, so i 
can see how far it gets?
