sane-epjitsu



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 col-
       lecting 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 fron-
              tends.

       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
       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)
       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
       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.
              The S1100 is not currently supported, but a patch is available.
