I recently bought a Samsung SCX-3405FW, and have had no issues printing with it. Unfortunately the scanner is a bit more troublesome. Under usb, sane-find-scanner detected the scanner, but I needed to force the xerox_mfp driver in order to get scanimage working (perhaps this model could be added to samsungmfp-scanner-sane-fix{,-multiarch}; the identifier is 04e8:344f).
Unfortunately, I haven't yet had much luck scanning over the network. At first, I could only detect the printer through netdiscovery; it wouldn't appear as a scanner either in scanimage or the configurator (although clicking on the configurator's scanner panel would cause the printer to emit warm-up noises). By clicking back and forth between the configurator's printer and scanner panels enough time, the scanner appeared, and also began to appear in the output of 'scanimage -L' (using the smfp backend, rather than the xerox_mfp backend). However, if I attempt to scan from this device, scanimage promptly segfaults. Additionally, if I click Properties in the configurator's scanner tab, it opens a new window which then closes almost instantly (I suspect this is the same issue augusto is experiencing).
Any help you can give would be appreciated. In particular, how can I force the xerox_mfp backend when connected over the network? I suspect that that by itself might solve my remaining scanning issues.
