sane-lexmark - SANE backend for Lexmark X1100/X1200 Series scanners
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.
The configuration file /etc/sane.d/lexmark.conf contains only the usb device id (eg usb 0x043d 0x007c).
/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).
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.
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.
No bugs currently known.

The backend was originally written by Fred Odendaal. http://email@example.com/ The new version is currently developed by Stphane Voltz. http://stef.dev.free.fr/sane/lexmark X74 support was written by Torsten Houwaart (<ToHo@gmx.de>)
Many thanks go to: Julien Furgerot who lend me a Dell A920. Robert Price, Dani Ele and Dalai Felinto for the time they spent recording USB activity and testing the experimental version. 12 Jul 2008 sane-lexmark(5)
