Hi! I need to handle duplex scanning via a Fujitsu fi4220c scanner. When I try to select CAP_DUPLEX, source return TWRC_FAILURE, TWCC_BADCAP. I set CAP_FEEDERENABLED and CAP_AUTOFEED to TRUE and set CAP_XFERCOUNT to either -1 or a multiple of 2 value :))). But it had not any results. 🙁 Please help me. 😳
To turn duplex scanning on or off, set the CAP_DUPLEXENABLED capability.
