sane-fujitsu



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 111, which  shipped  with  SANE
       1.0.23.


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 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.

              ------------ ------------ ------------
              ScanStation  M3093E/DE/EX fi-4110EOX/2
              ScanPartner  M3096EX      fi-4010CU
              SP-Jr        M3097E+/DE   S300/S300M

              SP-600C/620C              fi-5015C

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.


       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
              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.

       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.
