.SH NAME
|
|
sane\-fujitsu \- SANE backend for Fujitsu and Ricoh fi series scanners
|
|
|
|
.SH DESCRIPTION
|
|
The
|
|
.B sane\-fujitsu
|
|
library implements a SANE (Scanner Access Now Easy) backend which provides
|
|
access to most Fujitsu flatbed and ADF scanners, and the subsequent Ricoh models.
|
|
|
|
This document describes backend version 140.
|
|
|
|
.SH SUPPORTED HARDWARE
|
|
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, and most of the USB fi\-, ScanSnap, & iX series scanners are
|
|
supported. Please see the list at
|
|
.I http://www.sane\-project.org/sane\-supported\-devices.html
|
|
for details.
|
|
|
|
This backend may support other Fujitsu or newer Ricoh 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.
|
|
|
|
.SH UNSUPPORTED HARDWARE
|
|
The following scanners are known NOT to work with this backend,
|
|
either because they have an unsupported chipset, or an unsupported
|
|
interface type. Some of these scanners may be supported by another
|
|
backend.

.SH OPTIONS
|
|
Effort has been made to expose all hardware options, including:
|
|
.PP
|
|
.B source s
|
|
.RS
|
|
Selects the source for the scan. Options
|
|
may include "Flatbed", "ADF Front", "ADF Back", "ADF Duplex", "Card Front", "Card Back", "Card Duplex".
|
|
.RE
|
|
.PP
|
|
.B mode m
|
|
.RS
|
|
Selects the mode for the scan. Options
|
|
may include "Lineart", "Halftone", "Gray", and "Color".
|
|
.RE
|
|
.PP
|
|
.B resolution, y\-resolution
|
|
.RS
|
|
Controls scan resolution. Setting
|
|
.B \-\-resolution
|
|
also sets
|
|
.BR \-\-y\-resolution,
|
|
though this behavior is overridden by some frontends.
|
|
.RE
|
|
.PP
|
|
.B tl\-x, tl\-y, br\-x, br\-y
|
|
.RS
|
|
Sets scan area upper left and lower right coordinates. These are renamed
|
|
.B t, l, x, y
|
|
by some frontends.
|
|
.RE
|
|
.PP
|
|
.B page\-width, page\-height
|
|
.RS
|
|
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.
|
|
.RE
|
|
.PP
|
|
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
|
|
capabilities. 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.
|
|
.PP
|
|
.B swcrop
|
|
.RS
|
|
Requests the driver to detect the extremities of the paper within the larger
|
|
image, and crop the empty edges.
|
|
.RE
|
|
.PP
|
|
.B swdeskew
|
|
.RS
|
|
Requests the driver to detect the rotation of the paper within the larger
|
|
image, and counter the rotation.
|
|
.RE
|
|
.PP
|
|
.B swdespeck X
|
|
.RS
|
|
Requests the driver to find and remove dots of X diameter or smaller from the
|
|
image, and fill the space with the average surrounding color.
|
|
.RE
|
|
|
|
Use
|
|
.I '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.
|
|
|
|
.SH CONFIGURATION FILE
|
|
The configuration file
|
|
.I 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.
|
|
.PP
|
|
Scanners can be specified in the configuration file in 4 ways:
|
|
.PP
|
|
"scsi FUJITSU"
|
|
.RS
|
|
Requests backend to search all scsi buses in the system for a device
|
|
which reports itself to be a scanner made by 'FUJITSU'.
|
|
.RE
|
|
.PP
|
|
"scsi /dev/sg0" (or other scsi device file)
|
|
.RS
|
|
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.
|
|
.RE
|
|
.PP
|
|
"usb 0x04c5 0x1042" (or other vendor/product ids)
|
|
.RS
|
|
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.
|
|
.RE
|
|
.PP
|
|
"usb /dev/usb/scanner0" (or other device file)
|
|
.RS
|
|
Some systems use a kernel driver to access usb scanners. This method is
|
|
untested.
|
|
.RE
|
|
.PP
|
|
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.
|
|
.PP
|
|
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.
|
|
.PP
|
|
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.
|
|
.PP
|
|
|
|
.SH ENVIRONMENT
|
|
The backend uses a single environment variable,
|
|
.BR SANE_DEBUG_FUJITSU ,
|
|
which enables debugging output to stderr. Valid values are:

.SH KNOWN ISSUES
|
|
Flatbed units may fail to scan at maximum area, particularly at
|
|
high resolution.
|
|
.PP
|
|
Any model that does not support VPD during inquiry will not function until
|
|
an override is added to the backend.
|
|
.PP
|
|
CCITT Fax compression used by older scanners is not supported.
|
|
.PP
|
|
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.
|
|
.PP
|
|
Network interfaces are not supported on any scanner model.
