Hi, The backlight is not turned on for resolutions < 600 when scanning in Color mode. Scanning in 600 or 1200 DPI works fine. So this sucks for xsane preview mode for example.
I tried to move ~/.sane away. This has no effect though. This is the scanner: ID 04a9:190a Canon, Inc. CanoScan LiDE 210 The commandline is: $ export SANE_DEBUG_GENESYS=255 $ export SANE_DEBUG_GENESYS_LOW=255 $ scanimage --resolution 300 -y 5 --mode Color 2>dump300c >scan300c.pnm $ scanimage --resolution 600 -y 5 --mode Color 2>dump600c >scan600c.pnm $ scanimage --resolution 300 -y 5 --mode Gray 2>dump300g >scan300g.pnm All three dumps and scans are here: http://www.fi.muni.cz/~xslaby/sklad/lide210-dark/ thanks, -- js
