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 117, which  shipped  with  SANE
       1.0.24.


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 iX5xx 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".

       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 fron‐
              tends.

       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 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
       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 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.
