[sane-devel] phaser 6110MFP, no color mode

[Boris Samorodov]

Hi List,

I've got a used Xerox Phaser 6110MFP. Color mode is not functionning
as expected: color mode produces a greyscale image, Gray and Lineart
mode produces 1bit color image. 

Here are some logs:
-----
% export SANE_DEBUG_XEROX_MFP=4
% scanimage --format=tiff -l 1 -t 1 -x 100 -y 100 --mode color
[sanei_debug] Setting debug level of xerox_mfp to 4.

The resulting file is 8-bit Grayscale. BTW, I use 1.22 sane-backends
but it seems to detect itself as 1.21. ;-)
