|Scan Mode Options|
selects the basic mode of operation of the scanner valid choices are
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.
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:
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".
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 /usr/local/etc/sane.d/lexmark.conf contains only the usb device id (eg usb 0x043d 0x007c).
/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).
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 isnt supported for the X1200 series on USB 1.1, leading to slow scans.
No bugs currently known.

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.
