SANE Scanner Access Now Easy                      sane-epjitsu(5)



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 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 resolu-
     tions or scan area controls. See KNOWN ISSUES.

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


OPTIONS
     A limited effort  has  been  made  to  expose  the  standard
     options  to  the API.  This allows a frontend to set resolu-
     tion, 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  confi-
     guration  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.
          No  brightness,  contrast,  or  threshold  options  are
          exposed.
