## 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 Fujitsu flatbed and ADF 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-4220C
                  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 incor-
           porated.   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 document
           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 com-
           mand-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  mem-
                  ory.

           You  may specify the line "forceModel=xxx" in the configuration file to
           make the driver treat your scanner as an "xxx" scanner (currently  sup-
           ported:  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".

## LIMITATIONS

           Only tested with Linux 2.4

## 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
