NAME
sane-fujitsu - SANE backend for Fujitsu flatbed and ADF scanners
DESCRIPTION
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 137, which shipped with SANE
1.0.32.
SUPPORTED HARDWARE
This version supports every known model which speaks the Fujitsu SCSI
and SCSI-over-USB protocols. Specifically, the SCSI M309x and M409x se-
ries, the SCSI fi-series, most of the USB fi-series, the USB ScanSnap
S5xx/S15xx, and the USB iX1xx/5xx series 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 deter-
mine 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.
UNSUPPORTED HARDWARE
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.

OPTIONS
Effort has been made to expose all hardware options, including:
source s
Selects the source for the scan. Options may include "Flatbed",
"ADF Front", "ADF Back", "ADF Duplex", "Card Front", "Card
Back", "Card Duplex".
mode m
Selects the mode for the scan. Options may include "Lineart",
"Halftone", "Gray", and "Color".
resolution, y-resolution
Controls scan resolution. Setting --resolution also sets
--y-resolution, though this behavior is overridden by some
frontends.
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.
page-width, page-height
Sets paper size. Used by scanner to determine centering of scan
coordinates when using the ADF (Automatic Document Feeder) and
to detect double feed errors.
Other options will be available based on the capabilities of the scan-
ner: 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 ma-
chines to have similar capabilities. Please note that these features
are somewhat simplistic, and may not perform as well as the native im-
plementations. Note also that these features all require that the
driver cache the entire image in memory. This will almost certainly re-
sult in a reduction of scanning speed.
swcrop
Requests the driver to detect the extremities of the paper
within the larger image, and crop the empty edges.
swdeskew
Requests the driver to detect the rotation of the paper within
the larger image, and counter the rotation.
swdespeck X
Requests the driver to find and remove dots of X diameter or
smaller from the image, and fill the space with the average sur-
rounding color.
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 ad-
vanced options may be hidden by some frontend programs.
CONFIGURATION FILE
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 be unable to locate any
scanners.
Scanners can be specified in the configuration file in 4 ways:
"scsi FUJITSU"
Requests backend to search all scsi buses 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 buses in the system for a de-
vice 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 buf-
fer 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
this option.
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.
ENVIRONMENT
The backend uses a single environment variable, SANE_DEBUG_FUJITSU,
which enables debugging output to stderr. Valid values are:
5 Errors
10 Function trace
15 Function detail
20 Option commands
25 SCSI/USB trace
30 SCSI/USB writes
31 SCSI/USB reads
35 Useless noise
KNOWN ISSUES
Flatbed units may fail to scan at maximum area, particularly at high
resolution.
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.
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
source.
