you are trying to do an 8bit grayscale, duplex scan. i notice 1 thing now in the manual for the M3093DG: 'duplex reading supports only 0x01' (lineart) try setting --mode=lineart and see if that works. if so, i will update the backend to prevent you from trying :) allan > > .... truncated > > > if you need any more of the debug info just ask. > > Many thanks for your help > > Andi > > > > _______________________________________________ > sane-devel mailing list > [email protected] > http://lists.alioth.debian.org/mailman/listinfo/sane-devel > -- "so don't tell us it can't be done, putting down what you don't know. money isn't our god, integrity will free our souls" - Max Cavalera
