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 111, which shipped with SANE 1.0.23.

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, 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.

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".

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 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 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.

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.

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 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 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.

       Hardware automatic paper width detection (aka auto-cropping) 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.
