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!
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
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
- 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.
- 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)
The configuration file @CONFIGDIR@/lexmark.conf
contains only the usb device id (eg usb 0x043d 0x007c).
- 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 static library implementing this backend.
- The shared library implementing this backend (present on systems that support
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.
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.
No bugs currently known.

- The backend was originally written by Fred Odendaal.
- The new version is currently
developed by St[’e]phane Voltz.
- X74 support
was written by Torsten Houwaart (<ToHo@gmx.de>)
