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. > i have tried hard-setting this to all the possible (and some un-listed) > options, no change. i have tried different modes, no change. > > what is this option for (is is gamma correct or a pattern?) and what > should it be for lineart? 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. > how easy is it to get programming docs from fujitsu, since the 4120 seems > to need some help? > 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. Oliver
