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

       /usr/lib/arch_triplet/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.
