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 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).   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  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/x86_64-linux-gnu/sane/libsane-lexmark.a
              The static library implementing this backend.

       /usr/lib/x86_64-linux-gnu/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 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.

       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 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 series on USB 1.1, leading
       to slow scans.

BUGS

       No bugs currently known.
