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 133, which shipped with SANE 1.0.26.

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, 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  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 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 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.

       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.
