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


       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 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

              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).


       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.


              The static library implementing this backend.

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


              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
              usually be enough for a bug report.
