sane-epjitsu - SANE backend for Epson-based Fujitsu USB scanners.


   The  sane-epjitsu  library  implements a SANE (Scanner Access Now Easy)
   backend which provides  basic  access  the  Fujitsu  fi-60F/fi-65F  and
   ScanSnap S300/S1300/S1100 scanners.


   These  scanners  are  fairly limited, only supporting a couple of modes
   and resolutions, and always scanning full width. The  backend  supports
   missing  modes  (binary,  grayscale)  and  intermediate  resolutions in
   software, but provides only  minimal  scan  area  controls.  See  KNOWN

   This backend may support other scanners. If physical inspection reveals
   an Epson  chipset,  please  contact  the  author  for  instructions  on
   collecting a USB trace under Windows to verify.


   A  limited  effort  has been made to expose the standard options to the
   API.  This allows a frontend to set resolution, color mode, and  choose
   the  ADF  setting.  The  epjitsu  backend  supports the following basic
   options for most scanners:

   source s
          Selects the source for the scan. Options may include  "Flatbed",
          "ADF Front", "ADF Back", "ADF Duplex".

   mode m
          Selects  the  mode  for the scan. Options may include "Lineart",
          "Gray", "Color".

   resolution, y-resolution
          Controls  scan  resolution.  Setting  --resolution   also   sets
          --y-resolution,  though  this  behavior  is  overridden  by some

   Other options will be  available  based  on  the  capabilities  of  the
   scanner.  Use  'scanimage  --help'  to  get  a list. Be aware that some
   options may appear only when another option  has  been  set,  and  that
   advanced options may be hidden by the frontend.


   The  configuration  file "/etc/sane.d/epjitsu.conf" is used to tell the
   backend how to look for scanners, and provide options  controlling  the
   operation of the backend. This file is read each time the frontend asks
   the backend for a list of scanners, generally only  when  the  frontend
   starts.  If  the  configuration  file  is missing, the backend will not

   Scanners can be specified in the configuration file in two ways:

   "usb 0x04c5 0x10c7" (or other vendor/product ids)
          Requests backend to search all usb busses in the  system  for  a
          device  which  uses  that vendor and product id. The device will
          then be queried to determine if it is a supported scanner.

   "usb /dev/usb/scanner0" (or other device file)
          Some systems use a kernel driver to access  usb  scanners.  This
          method is untested.

   The  only  configuration  option supported is "firmware /PATH/TO/FILE",
   allowing you to  set  the  location  of  the  firmware  file  you  have
   extracted from the Windows driver.

   Note:  This  firmware  is  a  copyrighted work of Fujitsu, so cannot be
   provided by the backend or the author. Please do not ask.

   Note: These scanners REQUIRE a  firmware  file  to  function.  See  the
   supplied configuration file for more detail.

   Note:  This option may appear multiple times in the configuration file.
   It only applies to scanners discovered by 'usb' lines that follow  this


   The  backend  uses  a  single environment variable, SANE_DEBUG_EPJITSU,
   which enables debugging output to stderr. Valid values are:

          5  Errors
          10 Function trace
          15 Function detail
          20 Option commands
          25 USB trace
          30 USB detail
          35 Useless noise


          Only limited scan area options are exposed.
          fi-60F and fi-65F hardware grayscale mode is not used.

   fi-60F support funded by TrueCheck, Inc.
