Would it help if i contact Fujitsu and ask > them for a scsi programming manual for the 4120?? non standard. oliver and i both have the interface manual, what we dont have is time :) i have been experimenting with double feed and paper jam detection on the 4120 the past few days, and so have been looking at the manual in that area. it seems that the paperlength detection revolves around the scanner throwing an error when thedocument is smaller than the window length or defined paper length, and the driver catching the error. That does not seem all that useful, but perhaps i am missing something. the docs are poorly translated from japanese. you want a copy? allan > > /Mattias > > > -- > sane-devel mailing list: sane-devel@lists.alioth.debian.org > http://lists.alioth.debian.org/mailman/listinfo/sane-devel > Unsubscribe: Send mail with subject "unsubscribe your_password" > to sane-devel-requ...@lists.alioth.debian.org > -- "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

I don't know about the 4120, but the big brothers of that scanner are able to do a paper length detection. It works fine with TWAIN but I've not implemented it in SANE, yet. -- Oliver
[sane-devel] Fujitsu backend questions
Hello list, I have some questions about my fujitsu FI-4120C... (using the fujitsu = backend): - The scanner lamp is always on. From what I have heard, that is a Bad = Thing because it will shorten the lamp's lifetime... If this is correct, = then how can I turn off the lamp? Is there some magic hidden command to = do that? - Is there some way to make the scanner recognize the physical papersize = and scan only that size? Right now I have to select between A4 / A5 = paper format... If i use A4 then i know that the whole paper will always = be scanned.. but if i scan a lot of A5 then i want to scan only A5 = because it it twice as fast as A4 now when i mix A4 and the smaller = A5, I have to change settings all the time... If I use adfscan then I = have to set it to A4 (the largest format) but then i loose a lot of = speed... A 'papersize=3Dauto' feature would be nice... is there some way = to do this with the current backend? Thanks! /Mattias

no on both questions i think. there is a scsi command to set a timer on the lamp, but the backend does not send this command. should not be too hard to add. i have not investigated auto paper sizing, but it seems that it would only work for width, and would involve perhaps taking a single scanline at full width, and then determine most likely window params from that. this would be a bit more work. allan On Mon, 15 Nov 2004, Mattias Kregert wrote: > Hello list, > > I have some questions about my fujitsu FI-4120C...
