       sane-fujitsu - SANE backend for Fujitsu and Ricoh fi series scanners


       The  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.


       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, and most of the USB fi-, ScanSnap, & iX se-
       ries   scanners   are   supported.    Please   see    the    list    at 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.


       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.

              SCSI:        SERIAL:      USB:
              ------------ ------------ ------------
              ScanStation  M3093E/DE/EX fi-4110EOX/2
              ScanPartner  M3096EX      fi-4010CU
              SP-Jr        M3097E+/DE   S300/S300M
              SP-10/10C    M3099A/EH/EX S1300/S1100
              SP-15C/300C               fi-60F/65F
              SP-600C/620C              fi-5015C


       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

       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.

              Requests the driver to  detect  the  extremities  of  the  paper
              within the larger image, and crop the empty edges.

              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.


       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 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 supported 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.


       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


       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.

       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

       Network interfaces are not supported on any scanner model.
