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(1) or through GUI elements in xscanimage(1) or xsane(1).
If you notice 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). Gray mode 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.
CONFIGURATION FILE
The configuration file /etc/sane.d/lexmark.conf contains only the usb device id (eg usb
0x043d 0x007c).
FILES
/usr/lib/x86_64-linux-gnu/sane/libsane-lexmark.a
The static library implementing this backend.
/usr/lib/x86_64-linux-gnu/sane/libsane-lexmark.so
The shared library implementing this backend (present on systems that support
dynamic loading).
ENVIRONMENT
SANE_DEBUG_LEXMARK
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.
SANE_DEBUG_LEXMARK_LOW
Provides debug output for low level Lexmark functions.
LIMITATIONS
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.
BUGS
No bugs currently known.
