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 extra-
       neous helpful hints are available from the  backend  home-
       page:

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(i) 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  back-
       end 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 descrip-
              tion of SANE_CONFIG_DIR below).

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

       /usr/lib/sane/libsane-artec.so
              The shared library implementing this backend  (pre-
              sent 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 sepa-
              rator character, then the default  directories  are
              searched  after  the  explicitly specified directo-
              ries.   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

               Number  Remark
               0       print important errors
               1       print errors
               2       print sense
               3       print warnings
               4       print scanner-inquiry
               5       print informations
               6       print less important informations
               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 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 scan-
       ning.  3-channel gamma correction is not  implemented  and
       single-channel  gamma correction is not totally working on
       models other than the AT3.
