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

NAME
       sane-epsonds - SANE backend for EPSON ESC/I-2 scanners

DESCRIPTION
       The  sane-epsonds  library  implements a	SANE (Scanner Access Now Easy)
       backend that provides access to Epson ESC/I-2 scanners.

       Valid command line options and their syntax can be listed by using

	      scanimage	--help -d epsonds

       Not all devices support all options.

       Scan Mode
	      The --mode switch	selects	the basic mode	of  operation  of  the
	      scanner.	Valid choices are Lineart, Gray	and Color. The Lineart
	      mode is black and	white only, Gray will produce  256  levels  of
	      gray  or	more  depending	 on the	scanner	and Color means	24 bit
	      color mode or more depending on the scanner.  Some scanners will
	      internally use 36	bit color, their  external  interface  however
	      may only support 24 bits.

	      The  --depth  option selects the bit depth the scanner is	using.
	      This option is only available for	 scanners  that	 support  more
	      than  one	bit depth. Older scanners will always transfer the im-
	      age in 8bit mode.	Newer scanners allow one to  select  either  8
	      bits,  12	 or  14	 bits per color	channel. For a color scan this
	      means an effective color depth of	36 or 42 bits over  all	 three
	      channels.	The valid choices depend on the	scanner	model.

	      The  --resolution	switch selects the resolution for a scan. Some
	      EPSON scanners will scan in any resolution  between  the	lowest
	      and highest possible value. The list reported by the scanner can
	      be  displayed  using the "--help -d epson" parameters to scanim-
	      age(1).

	      The geometry options -l -t -x -y control the scan	area: -l  sets
	      the  top left x coordinate, -t the top left y coordinate,	-x se-
	      lects the	width and -y the height	of the scan area. All  parame-
	      ters are specified in millimeters.

	      The  --source  option selects the	scan source. Valid options de-
	      pend on the installed options. The default is "Flatbed".

	      The --eject option ejects	the sheet in the ADF.

	      The --adf-mode option select the ADF mode	(simplex/duplex).

CONFIGURATION FILE
       The configuration file /usr/local/etc/sane.d/epsonds.conf specifies the
       device(s) that the backend will use. Possible connection	types are:

       USB    For not automatically detected USB scanners,  their  VENDOR  and
	      PRODUCT  ID  can be specified manually in	the config file.  More
	      information about	valid syntax for USB devices can be  found  in
	      sane-usb(5).

       Network (not yet	supported)
	      Network  scanners	 can  be  auto-discovered  if autodiscovery is
	      specified	after net keyword.  An IP address to  connect  to  can
	      also be used.

FILES
       /usr/local/lib/sane/libsane-epsonds.a
	      The static library implementing this backend.

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

ENVIRONMENT
       SANE_DEBUG_EPSONDS
	      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. Values	around 11-16 will usu-
	      ally be enough for a bug report.
