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 image in
              8bit mode. Newer scanners allow 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 scanimage.

              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 selects the width and -y the height of the scan area. All parameters are
              specified in millimeters.

              The --source option selects the scan source. Valid options depend 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  /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/lib/arch_triplet/sane/libsane-epsonds.a
              The static library implementing this backend.

       /usr/lib/arch_triplet/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  environment  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 usuallybe enough for a bug report.
