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

       /usr/local/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  con‐
              figuration  file  is searched in two default directories: first,
              the  current   working   direc-   tory   (".")   and   then   in
              /usr/local/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 directo‐
              ries.  For example, setting  SANE_CONFIG_DIR  to  "/tmp/config:"
              would    result    in   directories   "tmp/config",   ".",   and
              "/usr/local/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

               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.
