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:
       http://www4.infi.net/~cpinkham/sane.

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/lib/x86_64-linux-gnu/sane/libsane-artec.a
              The static library implementing this backend.

       /usr/lib/x86_64-linux-gnu/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.  On *NIX systems, 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 directory (".") 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:

              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 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.
