Yes, the problem is really the gamma-pattern. I've hard-set this byte to
an invalid value and received the same error with the fujitsu-M4097.

According to the manual of the M3093 it is a gamma pattern. There are 
4 internal patterns (00h - 03h) and 8 download patterns (80h - 87h but
I don't know what that means).
The byte is valid for lineart (I can see differences in the scanned
image). The gamma pattern transforms the gray image before binarisation,
I guess.

You can find docs at
http://www.fel.fujitsu.com/home/documentation.asp?l=en&cid=9&doctype=oem&scpm=true
for some scanners, but I havn't found anything about the 4120.
I can give you an e-mail adress of somebody at fujitsu who might help. 
He gave me the documentation of the 4097 which is not on the 
fujitsu-homepage.
