       sane-artec - SANE backend for Artec flatbed scanners

       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:

       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.
       # 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.

       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.

	      The   backend   configuration  file  (see	 also  description  of
	      SANE_CONFIG_DIR below).

	      The static library implementing this backend.

	      The shared library implementing this backend (present on systems
	      that support dynamic loading).

	      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/lo-
	      cal/etc/sane.d" being searched (in this order).

	      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 informations
	       6       print less important informations
	       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 file

	       == 128  print out all messages

       Example:	export SANE_DEBUG_ARTEC=13

       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.
