Hi Martin! As some others posted, I have started something similar but did not come very far yet (also lack of time). The prog just scans in one page in the ADF and writes out a pnm or something. (http://cmp750.berlios.de). Maybe we could work together on a sane-backend to finally get the thing running ;-) Regards, Chris
