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.
