sane-epjitsu(5)          SANE Scanner Access Now Easy          sane-epjitsu(5)

       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(i)/S1100(i) 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 soft-
       ware, 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 col-
       lecting 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  op-
       tions 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 scan-
       ner. Use 'scanimage --help' to get a list. Be aware that  some  options
       may appear only when another option has been set, and that advanced op-
       tions may be hidden by the frontend.

       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

       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 ex-
       tracted from the Windows driver.

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

       Note:  These scanners REQUIRE a firmware file to function. See the sup-
       plied 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, because
              the calibration code is not finished.

       fi-60F support funded by TrueCheck, Inc.
