Hi, I have a (non-SANE) driver for network scanning using Dell 1600n, 1815dn, Ricoh FX200, Xerox Phaser 6110 and Samsung CLX-2160N MFP, see http://www.jon.demon.co.uk/dell1600n-net-scan/ I originally wrote the Dell 1600n part prior to writing a SANE backend (which I then did: dell1600n_net)

Looking inside of Xerox Phaser 3200MFP I see such chips that may help to identify compatible devices: Samsung CHORUSm - ARM processor. SCX-4725F/XRH V1.15(LF) - Samsung multifunction. ISP1582BS - Philips USB controller. Probably need to add chip detection to sane-find-scanner. On Sat, Jan 17,

Hi list, since I don't really like Samsung's binary Linux driver for SCX-4200 (which btw. works fine for me), and since it won't work on a mipsel box (openwrt distro) - and I got no answer on this from Samsung, I've decided to reverse engineer the protocol - which is, fortunately, quite trivial.
