NAME

       sane-fujitsu - SANE backend for Fujitsu flatbed scanners

DESCRIPTION

       The  sane-fujitsu  library  implements  a  SANE	(Scanner  Access  Now Easy) backend which provides access to Fujitsu flatbed scanners.	At
       present, the following scanners are known to work with this backend:

	      Vendor:  Model:		Rev:
	      -------- ---------------- -----
	      FUJITSU  M3096Gm		02
	      FUJITSU  M3093GX
	      FUJITSU  M3093GD
	      FUJITSU  M4097
	      FUJITSU  fi-4340C
	      FUJITSU  M3091DCd 	BF21
	      FUJITSU  M3092DCd

       The driver supports lineart, halftone, grayscale, and color (3091 and 3092) scanning depending on hardware capabiliites.

       The "Fujitsu" driver is a first attempt at integrating support for all Fujitsu scanners - previously available as different single  drivers
       -  in  one  driver.  At present, the M3091DCd is working (lineart, halftone, 8-bit grayscale and 24-bit color, simplex and duplex), and the
       driver should also support the M3096 as the M3096g driver code has been incorporated.  This driver  supersedes  the  old  "m3091"/"fujitsu"
       drivers and the old "m3096g" driver.

       Other  scanners	in these families may work.  The ScanPartner 15C seems to be a repackaging of the ScanPartner 600C, but I don't know if it
       works.  Look at the sp15c backend for this scanner.  Perusal of the M3096GX/M3093GX/M3093DG manual suggests the M3096G driver offers access
       to  a  subset  of  the new scanners.  People are encouraged to try these driver with the other scanners and to contact the author with test
       results.

DUPLEX MODE

       The M3091 driver supports duplex scanning. To the front-end, a duplex scan looks very much like scanning two separate pages from the  docu-
       ment  feeder, i.e. the SANE front-end receives two images instead of one.  Front-ends which are not capable of dealing with that - e.g. the
       command-line tool scanimage - cannot be used for duplex scanning.  If you want to do duplex scans from the command line, get Tom  Martone's
       scanadf program from http://www.martoneconsulting.com/sane-scanadf.html.

CONFIGURATION

       A  modest effort has been made to expose the standard options to the API.  This allows frontends such as xscanimage to set scanning region,
       resolution, bit-depth (and color), and enable the automatic document feeder.
       The "Fujitsu" driver supports the following options:
       mode m
	      m may be one of "Color", "Lineart", "Halftone", or "Gray", dependent on the scanner model. It is advisable to  specify  this  option
	      first when using command line tools, as the validity of some of the other options depends on the mode setting.

       x, y
	      Scan width and height

       pagewidth, pageheight
	      Page size; when using the ADF, the driver will assume that a page of the given width is centered

       resolution, y-resolution
	      Controls scan resolution. Permissible values dependent on model and scan mode; setting --resolution also sets --y-resolution but not
	      vice versa. This makes it possible to set the 3091's maximum resolution of 300x600dpi.

       brightness b
	      Only supported for M3096

       treshold t
	      Only supported for M3096

       duplex d
	      d may be "front", "back", or "both" and denotes which sides of the page are to be scanned (duplex scanner  only  for  example  3091,
	      3093Gd).

       lampcolor c
	      c may be "red", "green", "blue", or "default" - the lamp color to be used when doing graysacale or b/w scans on the M3091.

       blueoffset, greenoffset
	      Color  justification  options  for the M3091; anything other than +1/-1 will probably distort the image. Should be left alone unless
	      your scanner is buggy.

       swapfile
	      boolean option for the M3091. Only affects duplex scans. If set, a swap file will be used for storing the rear side of a document as
	      it is scanned; otherwise the whole page will be kept in memory.

       You  may  specify  the line "forceModel=xxx" in the configuration file to make the driver treat your scanner as an "xxx" scanner (currently
       supported: 3096, 3091). Use this if you have another scanner that is not automatically detected as being compatible.

       The only other configuration option supported is "scsi-buf-size=xxx", allowing you to set the SCSI buffer size to something other than  the
       compiled-in  default.  Especially  with	the M3091 scanner, some users had the problem that the scanner would "hang" mid-page, and this can
       often be alleviated by using "scsi-buf-size=32768".

BUGS

       I'm  sure there are plenty, and not too well hidden, but I haven't seen them yet.  I don't know if the ScanPartner 15C still works, because
       I'm not able to test it.  3091/3092 don't support halftone
