sane-epjitsu - SANE backend for Epson-based Fujitsu USB scanners.
library implements a SANE (Scanner Access Now Easy)
backend which provides basic access the Fujitsu fi-60F/fi-65F and ScanSnap
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.
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:
Selects the source for the scan. Options may
include "Flatbed", "ADF Front", "ADF Back",
Selects the mode for the scan. Options may
include "Lineart", "Gray", "Color".
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 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 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.
This firmware is a copyrighted work of Fujitsu, so cannot be
provided by the backend or the author. Please do not ask.
These scanners REQUIRE a firmware file to function. See the
supplied configuration file for more detail.
This option may appear multiple times in the configuration file. It
only applies to scanners discovered by 'usb' lines that follow this option.
The backend uses a single environment variable, SANE_DEBUG_EPJITSU, which
enables debugging output to stderr. Valid values are:
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.

fi-60F support funded by TrueCheck, Inc.
