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

       /usr/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

               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.
