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 consti-
       tutes 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 scan-
       ner 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
       @CONFIGDIR@/artec.conf
              The   backend   configuration  file  (see  also  description  of
              SANE_CONFIG_DIR below).

       @LIBDIR@/libsane-artec.a
              The static library implementing this backend.

       @LIBDIR@/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  con-
              figuration  file  is searched in two default directories: first,
              the current working direc- tory (".") and then  in  @CONFIGDIR@.
              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, set-
              ting SANE_CONFIG_DIR to "/tmp/config:" would result in  directo-
              ries  "tmp/config",  ".",  and  "@CONFIGDIR@" being searched (in
              this order).

       SANE_DEBUG_ARTEC
              If the library was compiled with debug support enabled, this en-
              vironment  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

              Number  Remark
               0       print important errors
               1       print errors
               2       print sense
               3       print warnings
               4       print scanner-inquiry
               5       print information
               6       print less important information
               7       print major called procedures
               8       print all called procedures
               9       print procedure info/data messages
               10      print called sane-init-routines
               11      print called sane-procedures
               12      print sane infos
               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 ear-
       lier 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.
