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 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 se-
       ries,  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.

	      --------------------------------------
	      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	fi-60F
	      SP-15C/300C		fi-5015C
	      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	 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 capabilites. Please note that these features are
       somewhat	 simplistic,  and may not perform as well as the native	imple-
       mentations. 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 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 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.

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.
