sane-coolscan(5)	 SANE Scanner Access Now Easy	      sane-coolscan(5)

NAME
       sane-coolscan - SANE backend for	Nikon film-scanners

ABOUT THIS FILE
       This file is a short description	of the coolscan	backend	for SANE.

DESCRIPTION
       The  sane-coolscan  library implements a	SANE backend that provides the
       interface to the	following Nikon	Coolscan Film  scanners:  Nikon	 LS20,
       LS30, LS1000, LS2000.

       Even  though  the  backend has worked for a number of people, there are
       still  some  problems,  especially  in  combination  with   some	  SCSI
       card/drivers  (AHA-1505/aha152x.o)  and	the  autofocus	command.   You
       should consider this backend 'alpha' and	be careful when	using  it  the
       first time.

CONFIGURATION
       The   configuration   file   for	  this	backend	 resides  in  /usr/lo-
       cal/etc/sane.d/coolscan.conf.

       Its content is a	list of	device names that correspond to	Nikon Coolscan
       scanners.  Empty	 lines and lines starting with a hash mark (#) are ig-
       nored. A	sample configuration file is shown below:

	#scsi Vendor Model Type
	scsi Nikon * Scanner
	/dev/scanner

       The special device name must be a generic SCSI device or	a  symlink  to
       such  a	device.	  To find out to which device your scanner is assigned
       and how you can set the permissions of that  device,  have  a  look  at
       sane-scsi(5).

SCSI ADAPTER TIPS
       Some  SCSI-adapters  and	 low-level  SCSI drivers do not	work correctly
       with this backend and the Coolscan scanners. These  systems  hang  when
       the  autofocus  command is send to the Scanner.	To see a list of which
       card/driver combinations	work or	don't work have	a look at:  http://an-
       dreas.rick.free.fr/sane/autofocus.html.

FILES
       The backend configuration file:
	      /usr/local/etc/sane.d/coolscan.conf

       The static library implementing this backend:
	      /usr/local/lib/sane/libsane-coolscan.a

       The shared library implementing this backend:
	      /usr/local/lib/sane/libsane-coolscan.so (present on systems that
	      support dynamic loading)

ENVIRONMENT
       SANE_DEBUG_COOLSCAN
	      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.

	      Examples:

	      On bash:
	      export SANE_DEBUG_COOLSCAN=8

	      On csh:
	      setenv SANE_DEBUG_COOLSCAN 8

BUGS
       The autofocus command does not work with	some SCSI card/driver combina-
       tions.

       The gamma table is not implemented for the LS1000 yet.

       The dust-removal	is not working yet.

THANKS TO
       Didier Carlier -	For writing the	original Coolscan backend (without  it
       I would not have	started	this).

       Oliver Rauch - For adapting xsane so quickly to the infrared stuff.

       All the other people working on SANE.
