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
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/sane/libsane-lexmark.a
The static library implementing this backend.
/usr/lib/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
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 serie on USB 1.1,
leading to slow scans.
BUGS
No bugs currently known.
