[sane-devel] genesys: canon lide 210 produces black color scans

[Jiri Slaby]

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:
