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 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/lo-
	      cal/etc/sane.d.  If the value of the environment	variable  ends
	      with  the	directory separator character, then the	default	direc-
	      tories are searched after	the explicitly specified  directories.
	      For example, setting SANE_CONFIG_DIR to "/tmp/config:" would re-
	      sult in directories tmp/config, ., and /usr/local/etc/sane.d be-
	      ing searched (in this order).

       SANE_DEBUG_ARTEC
	      If the library was compiled with debug support enabled, this en-
	      vironment	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  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.
