sane-fujitsu(5)		 SANE Scanner Access Now Easy	       sane-fujitsu(5)

       sane-fujitsu - SANE backend for Fujitsu flatbed and ADF scanners

       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	the  rewritten	backend	 versions  1.0.21  and

       The  backend  supports lineart, halftone, grayscale, and color scanning
       for most USB and SCSI scanners,	depending  on  hardware	 capabilities.
       Most  simple  scanning related features are exposed.  This version fea‐
       tures at least basic support for many more models.  See KNOWN ISSUES.

       The following scanners are thought to  have  at	least  basic  scanning
       capability,  either because they have been tested with a prior version,
       or because documentation indicates they are compatible  with  a	tested

       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.

       This  backend  may  support  scanners  not listed here. The best way to
       determine level of support is to test the  scanner  directly.   Fujitsu
       equipment has historically been good enough to not be damaged by incor‐
       rect commands if the  scanner  is  incompatible.	  Please  contact  the
       author with test results, positive or negative.

       A  modest  effort  has  been made to expose the standard options to the
       API.  This allows a frontend to set scanning region,  resolution,  bit-
       depth,  color  mode,  and  enable  the  automatic  document feeder. The
       fujitsu backend supports the following basic options for most scanners:

       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  but  not  vice versa. This behavior is overridden by
	      some frontends.

       tlx, tly, brx, bry
	      Sets scan area upper left and  lower  right  coordinates.	 Often
	      converted to t, l, x, y by frontend code.

       pagewidth, pageheight
	      Sets  paper size. Used by scanner to determine centering of scan
	      coordinates when using ADF.

       Other options will be available based on the capabilities of the	 scan‐
       ner.   Use 'scanimage --help' to get a list. Be aware that some options
       may appear only when another option has been set.

       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 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 detail

       Backend	versions  prior to this were numbered with a two part version,
       or with no version number at all. At the time this version was written,
       all older versions were retroactively renumbered, 1.0.2 - 1.0.20.

       The  current  backend  may  have lost support for some feature you were
       using.  The last of the "old" backends, 1.0.20, is still	 available  as
       source from:

       If  you find that you need to use the older version, please contact the
       author, to try and get those features restored to a later version.

	      All IPC, imprinter, and compression options are disabled.
	      Most scanner specific 'quirks' are not accounted for, making  it
	      possible	to  set some options in ways that the scanner does not
