Karsten Festag <karsten.festag@t-online.de> is the maintainer of the
microtek2 backend.

From a quick look into the code I suspect that scsi_sense_handler()
Status: O

checks for the respective sense code and returns SANE_STATUS_NO_DOCS.
Maybe the status is not detected correctly or lost later in the code.

A debugging output (SANE_DEBUG_SANEI_SCSI=255 SANE_DEBUG_MICROTEK2=255
in this case) may help to find the exact source.

Concerning your little discussion on bugzilla: I'm sure every backend
maintainer tries to make his backend report errors as specific as
possible. SANE has more error codes than SANE_STATUS_IO_ERROR so
usually that's not a big problem. Bug reports are always welcome :-)

Bye,
