NAME

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

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 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.

CONFIGURATION FILE

       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.

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 control by the user,
       including: multifeed detection, image compression, autocropping, endorser,  iThresholding,
       multi-stream, etc.
