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 sane-epjitsu backend supports the following basic
options for most scanners:
Selects the source for the scan. Options may include "Flatbed",
"ADF Front", "ADF Back", "ADF Duplex".
Selects the mode for the scan. Options may include "Lineart",
Controls scan resolution. Setting --resolution also sets
--y-resolution, though this behavior is overridden by some fron-
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.
The configuration file /usr/local/etc/sane.d/epjitsu.conf is used to
tell the backend how to look for scanners, and provide options control-
ling 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 buses 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 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:
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.
S300 support funded by Microdea, Inc. and Archivista, GmbH.
fi-60F support funded by TrueCheck, Inc.
Improved calibration code provided by Richard Goedeken.
