SANE Scanner Access Now Easy sane-epjitsu(5)
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 scanners.
HARDWARE SUPORT
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 resolu-
tions or scan area controls. See KNOWN ISUES.
This backend may support other scanners. If physical inspec-
tion reveals an Epson chipset, please contact the author for
instructions on collecting a USB trace under Windows to ver-
ify.
OPTIONS
A limited effort has been made to expose the standard
options to the API. This allows a frontend to set resolu-
tion, 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 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 confi-
guration file. It only applies to scanners discovered by
'usb' lines that follow this option.
ENVIRONMENT
The backend uses a single environment variable,
SANEDEBUGEPJITSU, 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 ISUES
No scan area options are exposed.
No brightness, contrast, or threshold options are
exposed.
