NAME

       sane-lexmark - SANE backend for Lexmark X1100/X1200 Series scanners

DESCRIPTION

       The  sane-lexmark  library  implements a SANE (Scanner Access Now Easy)
       backend that provides access to the scanner part of Lexmark X1100/X1200
       AIOs. This backend should be considered beta-quality software!

       The scanners that should work with this backend are:

                 Vendor Model           status
              ----------------------  -----------
                Lexmark X74             good
                Lexmark X1110           untested
                Lexmark X1140           untested
                Lexmark X1150           good
                Lexmark X1170           good
                Lexmark X1180           good
                Lexmark X1185           complete
                Lexmark X12xx           good in USB1.1,
                                        not fully tested in USB2.0
                Dell    A920            good

       The options the backend supports can either be selected through command
       line options to programs like scanimage(1) or through GUI  elements  in
       xscanimage(1) or xsane(1).

       If  you notice any strange behavior, please report to the backend main-
       tainer or to the SANE mailing list.

       Valid command line options and their syntax can be listed by using

              scanimage --help -d lexmark:usb:<usb port>

       Scan Mode Options

       --mode selects the basic  mode  of  operation  of  the  scanner.  Valid
              choices are Color, Gray and Lineart.  The default mode is Color.
              The Lineart mode is black and white only  (1  bit).   Gray  mode
              will produce 256 levels of gray (8 bits).  Color mode allows for
              over 16 million different colors produced from 24 bits of  color
              information.

       --resolution
              selects  the  resolution for a scan. The horizontal and vertical
              resolutions are set by the value of this option. The scanner  is
              capable  of  the  following resolutions for the specified option
              value:

                Value   Hor. Resolution  Vert. Resolution
                -----   ---------------  -------------------
                75      75dpi            75dpi
                150     150dpi           150dpi
                300     300dpi           300dpi
                600     600dpi           600dpi
                1200    600dpi           1200dpi  (only for X11xx models with 'B2' sensor)

       --preview
              requests a preview scan. The resolution used for that scan is 75
              dpi and the scan area and the scan mode are as specified through
              their options, or the default  if  not  specified.  The  default
              value for preview mode is "no".

       --threshold
              selects  the   minimum-brightness  to  get  a  white  point. The
              threshold is only used with Lineart mode scans.  It is specified
              as  a  percentage in the range 0..100% (in steps of 1).  The de-
              fault value of the threshold option is 50.

CONFIGURATION FILE

       The configuration file /usr/local/etc/sane.d/lexmark.conf contains only
       the usb device id (eg usb 0x043d 0x007c).

FILES

       /usr/local/lib/sane/libsane-lexmark.a
              The static library implementing this backend.

       /usr/local/lib/sane/libsane-lexmark.so
              The shared library implementing this backend (present on systems
              that support dynamic loading).

ENVIRONMENT

       SANE_DEBUG_LEXMARK
              If the library was compiled with debug support enabled, this en-
              vironment  variable  controls  the debug level for this backend.
              E.g., a value of 255 requests all debug output  to  be  printed.
              Smaller levels reduce verbosity.

       SANE_DEBUG_LEXMARK_LOW
              Provides debug output for low level Lexmark functions.

LIMITATIONS

       The  windows TWAIN driver has many more options than this SANE backend.
       However they are only software adjustments. This  backend  only  imple-
       ments  what  the  scanner can support. For instance, shading correction
       (vertical stripes due to sensor variation across its width) is done  in
       software.  Head  park  position is also detected by software.  The data
       compression isn't supported for the X1200 series on USB 1.1, leading to
       slow scans.

BUGS

       No bugs currently known.
