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 93, which shipped with SANE
       1.0.20.

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   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.

              SP-600C/620C

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.

       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.

       Automatic paper size 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.
