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 98, which shipped with SANE
       1.0.21.

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 capabilites. 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 use a set of compiled
       defaults, which are identical to the default configuration file shipped
       with SANE.

       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 detail
              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.
