The problem that we commonly see with devices using the xerox_mfp 
backend that used to work before are related to a change to enable JPEG 
compression.
However, it transpires that some of these devices do not support it.

Could you let us see the output of the diag from the xerox_mfp backend?

SANE_DEBUG_XEROX_MFP=4 ...

I only see the output from SANE_DEBUG_DLL.

Cheers,
Ralph
