Hope you are having a great day. The output from the command as follow:

I have already tried both and both didn't scan. The result from the
previous email is from the xerox_mfp one
Thank you very much.
Could you let us see some diag output from the xerox_mfp backend?
SANE_DEBUG_XEROX_MFP=50 scanimage {whatever options you use}
If there is a *lot* of output, perhaps just send it to me as an attachment.
Cheers,
Ralph
