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 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 capa-
	      ble 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 per-
	      centage 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/lib64/sane/libsane-lexmark.a
	      The static library implementing this backend.

       /usr/lib64/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 serie on USB 1.1, leading to
       slow scans.

BUGS

       No bugs currently known.
