sane-fujitsu - SANE backend for Fujitsu flatbed and ADF scanners
The sane-fujitsu library implements a SANE (Scanner Access Now Easy)
backend which provides access to most Fujitsu flatbed and ADF scanners.
This document describes backend version 98, which shipped with SANE
This version supports every known model which speaks the Fujitsu SCSI
and SCSI-over-USB protocols. Specifically, the SCSI M309x and M409x
series, the SCSI fi-series, most of the USB fi-series, and the USB
ScanSnap S5xx/S15xx scanners are supported. Please see the list at
http://www.sane-project.org/sane-supported-devices.html for details.
This backend may support other Fujitsu scanners. The best way to
determine level of support is to test the scanner directly, or to
collect a trace of the windows driver in action. Please contact the
author for help or with test results.
The following scanners are known NOT to work with this backend, either
because they have a non-fujitsu chipset, or an unsupported interface
type. Some of these scanners may be supported by another backend.

Effort has been made to expose all hardware options, including:
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",
"Halftone", "Gray", and "Color".
Controls scan resolution. Setting --resolution also sets
--y-resolution, though this behavior is overridden by some
tl-x, tl-y, br-x, br-y
Sets scan area upper left and lower right coordinates. These are
renamed t, l, x, y by some frontends.
Sets paper size. Used by scanner to determine centering of scan
coordinates when using ADF and to detect double feed errors.
Other options will be available based on the capabilities of the
scanner: machines with IPC or DTC will have additional enhancement
options, those with CMP will have compression options, those with a
printer will have a group of endorser options.
Additionally, several ’software’ options are exposed by the backend.
These are reimplementations of features provided natively by larger
scanners, but running on the host computer. This enables smaller
machines to have similar capabilites. Please note that these features
are somewhat simplistic, and may not perform as well as the native
implementations. Note also that these features all require that the
driver cache the entire image in memory. This will almost certainly
result in a reduction of scanning speed.
Use ’scanimage --help’ to get a list, but be aware that some options
may be settable only when another option has been set, and that
advanced options may be hidden by some frontend programs.
The configuration file "fujitsu.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 use a set of compiled
defaults, which are identical to the default configuration file shipped
Scanners can be specified in the configuration file in 4 ways:
Requests backend to search all scsi busses in the system for a
device which reports itself to be a scanner made by ’FUJITSU’.
"scsi /dev/sg0" (or other scsi device file)
Requests backend to open the named scsi device. Only useful if
you have multiple compatible scanners connected to your system,
and need to specify one. Probably should not be used with the
other "scsi" line above.
"usb 0x04c5 0x1042" (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 Fujitsu 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 "buffer-size=xxx", allowing
you to set the number of bytes in the data buffer to something other
than the compiled-in default, 65536 (64K). Some users report that their
scanner will "hang" mid-page, or fail to transmit the image if the
buffer is not large enough.
Note: This option may appear multiple times in the configuration file.
It only applies to scanners discovered by ’scsi/usb’ lines that follow
Note: The backend does not place an upper bound on this value, as some
users required it to be quite large. Values above the default are not
recommended, and may crash your OS or lockup your scsi card driver. You
have been warned.
The backend uses a single environment variable, SANE_DEBUG_FUJITSU,
which enables debugging output to stderr. Valid values are:
10 Function trace
15 Function detail
20 Option commands
25 SCSI/USB trace
30 SCSI/USB detail
35 Useless noise
Flatbed units may fail to scan at maximum area, particularly at high
Any model that does not support VPD during inquiry will not function
until an override is added to the backend.
CCITT Fax compression used by older scanners is not supported.
Hardware automatic paper width detection (aka auto-cropping) is not
JPEG output is supported by the backend, but not by the SANE protocol,
so is disabled in this release. It can be enabled if you rebuild from
