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

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 127, which  shipped  with  SANE
       1.0.25.

SUPPORTED HARDWARE
       This  version  supports every known model which speaks the Fujitsu SCSI
       and SCSI-over-USB protocols. Specifically, the SCSI M309x and M409x se-
       ries,  the  SCSI	fi-series, most	of the USB fi-series, the USB ScanSnap
       S5xx/S15xx, and the USB iX1xx/5xx 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.

	      --------------------------------------
	      SCSI:	   SERIAL:	USB:
	      ------------ ------------	------------
	      ScanStation  M3093E/DE/EX	fi-4110EOX/2
	      ScanPartner  M3096EX	fi-4010CU
	      SP-Jr	   M3097E+/DE	S300/S300M
	      SP-10/10C	   M3099A/EH/EX	S1300/S1100
	      SP-15C/300C		fi-60F
	      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
	      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 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  ma-
       chines  to  have	 similar capabilities. Please note that	these features
       are somewhat simplistic,	and may	not perform as well as the native  im-
       plementations.  Note  also  that	 these	features  all require that the
       driver cache the	entire image in	memory.	This will almost certainly re-
       sult 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  ad-
       vanced 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.
