Description:

Sane (sane-project) 1.0.21 introduced a bug in xerox_mfp backend which is affecting multiple devices (samsung, xerox). Due to this bug no (true)color scanning is possible - only grayscale and lineart modes are possible.

There is a fix already in upstream git:

diff --git a/backend/xerox_mfp.c b/backend/xerox_mfp.c
index cda6e82..e6ede0d 100644
--- a/backend/xerox_mfp.c

SANE_VALUE_SCAN_MODE_LINEART,
+ SANE_VALUE_SCAN_MODE_HALFTONE,

NULL

I suggest to adopt the patch until the new version is released (as this is clearly a regression).
