## 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 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 Lin‐
                  eart mode is black and white only (1 bit).  Grayscale will  pro‐
                  duce  256 levels of gray (8 bits). Color mode allows for over 16
                  million different colors produced from 24 bits of color informa‐
                  tion.

           --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 /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
                  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  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.
