Hi, there. I'm currently playing around with the SANE API. When listing all options available for my scanner (Canon N670U a.k.a LiDE 20) I noticed an option called "lamp-switch". It provides a description saying it's for "Manually switching the lamp(s).".
Does that mean that the scanner supports scanning with the lamps off? (e.g. to scan negatives)? If so, how should I use that option? I tried setting it to 1 just bevore starting the scan, but I didn't see any changes. Also, is there any comprehensive documentation about the various options each backand provieds? I checked the manpages, but the "lamp-switch" option doesn't seem to be documented there.
