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  fron-
       tend 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.
	      The S1100 is not currently supported, but a patch is available.
