That's SANE_STATUS_NO_DOCS which is to be expected for --batch scans.
I'd say scanimage should return EXIT_SUCCESS for --batch scans if and
only if it has successfully acquired at least one image.  That is,
starting a --batch scan without any originals in the feeder should still
return SANE_STATUS_NO_DOCS.

Hope this helps,
