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  and  ScanSnap
       S300/S1300 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) in software, but makes no effort to
       offer intermediate resolutions or 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 "/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
       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

              No scan area options are exposed.
              fi-60F hardware grayscale mode is not used.
