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 or through GUI elements in
       xscanimage or xsane.

       If you have any strange behavior, please report to the backend
       maintainer 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).  Grayscale 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
              default value of the threshold option is 50.



CONFIGURATION FILE
       The configuration file /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
              SANE_DEBUG_LEXMARK_LOW If the library was compiled with debug
              support enabled, this environment 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.



LIMITATIONS
       The windows TWAIN driver has many more options than this SANE backend.
       However they are only software adjustments. This backend only
       implements 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 serie on USB 1.1,
       leading to slow scans.


BUGS
       No bugs currently known.
