       sane-kodak - SANE backend for big Kodak flatbed and ADF scanners


       The  sane-kodak  library  implements  a  SANE (Scanner Access Now Easy)
       backend which provides access to large Kodak flatbed and ADF  scanners.

       This  document  describes  backend  version  7, which shipped with SANE


       This version should support models  which  speak  the  Kodak  SCSI  and
       Firewire  protocols.  The  i1860  was  used to develop the backend, but
       other models may work with only minimal modifications. Please  see  the
       list  at for an
       updated list.

       If you have a machine not on that list, or reported as ’untested’:  the
       best way to determine 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.


       Most of the recent Kodak consumer or workgroup level machines are based
       on other chipsets and are not supported by this backend. Some of  these
       scanners may be supported by another backend.


       Effort has been made to expose the basic 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".

              Controls  scan  resolution.  Available choices may be limited by

       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
       scanner.   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
       advanced options may be hidden by some frontend programs.


       The  configuration file "kodak.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 2 ways:

       "scsi KODAK"
              Requests  backend  to search all scsi busses in the system for a
              device which reports itself to be a scanner made by ’KODAK’.

       "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.

       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, 32768 (32K). Some users report that their
       scanner will "hang" mid-page, or fail to  transmit  the  image  if  the
       buffer 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_KODAK, which
       enables debugging output to stderr. Valid values are:

              5  Errors
              10 Function trace
              15 Function detail
              20 Option commands
              25 SCSI trace
              30 SCSI detail
              35 Useless noise


       Most  hardware  options  are  either  not  supported or not exposed for
       control by the user, including: multifeed detection, image compression,
       autocropping, endorser, iThresholding, multi-stream, etc.


       The various authors of the sane-fujitsu backend provided useful code.
       Kodak provided access to hardware, documentation and personnel.
