NAME
       sane-artec - SANE backend for Artec flatbed scanners


DESCRIPTION
       The sane-artec library implements a SANE (Scanner Access Now Easy)
       backend that provides access to Artec/Ultima SCSI flatbed scanners.  At
       present, the following scanners are known to work at least partially
       with this backend:

              * Artec A6000C
              * Artec A6000C PLUS
              * Artec ViewStation AT3
              * BlackWidow BW4800SP (rebadged Artec AT3)
              * Artec ViewStation AT6
              * Artec ViewStation AT12
              * Artec AM12S
              * Plustek 19200S (rebadged Artec AM12S)

       Although this manual page is generally updated with each release, up-
       to-date information on new releases and extraneous helpful hints are
       available from the backend homepage:

DOCUMENTATION
CONFIGURATION
       The contents of the artec.conf file are a list of device names that
       correspond to Artec scanners.  Empty lines and lines starting with a
       hash mark (#) are ignored.  See sane-scsi(5) on details of what
       constitutes a valid device name.

       Sample file:
       # artec.conf
       #
       # this is a comment.
       #
       # this line says search for any SCSI devices which are scanners and have
       #     a vendor string of 'ULTIMA'
       scsi ULTIMA
       #
       # the next line forces the backend to assume the next scanner found has
       #     the specified vendor string (useful for testing rebadged models).
       vendor ULTIMA
       #
       # the next line forces the backend to assume the next scanner found has
       #     the specified model string (useful for testing rebadged models).
       model AT3
       #
       # now a line that actually specifies a device.  The backend is going to
       #     assume this is an Artec/Ultima AT3 because we forced the vendor and
       #     model above.
       /dev/scanner
       #
       # once we hit a scanner device line, the forced vendor and model
       # string are
       #     'forgotten', so the vendor and model for this next device will be
       #     determined from the result of a SCSI inquiry.
       /dev/sge
       #


SCSI ADAPTER TIPS
       Some Artec scanners come with an included SCSI adapter.  If your
       scanner came with a DTC ISA scsi cards, you can probably use it with
       recent (>= 2.2.0) kernels using the generic NCR5380 support.  You must
       pass the following boot argument to the kernel: "dtc3181e=0x2c0,0"
       I do not have any information on the PCI SCSI adapter included with
       some newer Artec scanners.


FILES
       /etc/sane.d/artec.conf
              The backend configuration file (see also description of
              SANE_CONFIG_DIR below).

       /usr/local/lib/sane/libsane-artec.a
              The static library implementing this backend.

       /usr/local/lib/sane/libsane-artec.so
              The shared library implementing this backend (present on systems
              that support dynamic loading).

ENVIRONMENT
       SANE_CONFIG_DIR
              This environment variable specifies the list of directories that
              may contain the configuration file.  Under UNIX, the directories
              are separated by a colon (`:'), under OS/2, they are separated
              by a semi- colon (`;').  If this variable is not set, the
              configuration file is searched in two default directories:
              first, the current working direc- tory (".") and then in
              /etc/sane.d.  If the value of the environment variable ends with
              the directory separator character, then the default directories
              are searched after the explicitly specified directories.  For
              example, setting SANE_CONFIG_DIR to "/tmp/config:" would result
              in directories "tmp/config", ".", and "/etc/sane.d" being
              searched (in this order).

       SANE_DEBUG_ARTEC
              If the library was compiled with debug support enabled, this
              environment variable controls the debug level for this backend.
              E.g., a value of 128 requests all debug output to be printed.
              Smaller levels reduce verbosity: SANE_DEBUG_ARTEC values

               13      print sane option-control messages

               50      print verbose data/debug messages

               == 100  print software RGB calibration data
               == 101  print raw data from scanner to artec.data.raw file

               == 128  print out all messages

       Example: export SANE_DEBUG_ARTEC=13


BUGS
       Known bugs in this release: A6000C+ users with firmware v1.92 or
       earlier have problems with the backend, the cause has not been
       determined.  Sometimes the backend is not particularly robust, you can
       possibly lock up the SCSI bus (and/or machine) by not having patience
       enough when scanning.  3-channel gamma correction is not implemented
       and single-channel gamma correction is not totally working on models
       other than the AT3.
