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.
