sane-kodak



DESCRIPTION
       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
       1.0.21.


SUPPORTED HARDWARE
       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 http://www.sane-project.org/sane-supported-devices.html 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.


UNSUPPORTED HARDWARE
       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.


OPTIONS
       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".

       resolution
              Controls scan resolution. Available choices may  be  limited  by
              mode.

       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.  Use 'scanimage --help' to get a list,  but  be  aware  that  some
       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 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_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


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