Set Fujitsu SDTC mode

[Jose Silva]

Anyone knows how to set the binarization mode of a fujitsu scanner?

On the twain dialog it appears under Black/White item and have the possibilities:
Static Threshold
SDTC mode
Advanced DTC

What is the triplet sequence to use to change this value?

search the forum, there was a rather clever hack to getting to more control from those scanners. had to do with editing the CustomDsData, the poster said something about it even being a recommendation from fujitsu.

otherwise those don’t seem like standard capabilities (the kind you see defined in the spec), course they might be in there in an odd section I fail to remember – correct me if I’m wrong here.
If they aren’t in the twain spec then you have to go to the vendor unless you can find/edit it in the CustomDsData
