• 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

• 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.
