NAME

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

DESCRIPTION

       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(i)/S1100(i) scanners.

HARDWARE SUPPORT

       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 ISSUES.

       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.

OPTIONS

       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 frontends.

       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.

CONFIGURATION FILE

       The  configuration  file "@CONFIGDIR@/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 work.

       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 option.

ENVIRONMENT

       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

KNOWN ISSUES

              Only limited scan area options are exposed.
              fi-60F and fi-65F hardware grayscale mode is  not  used,  because  the  calibration  code  is  not
              finished.
