<H2>NAME</H2><PRE>
sane-lexmark - SANE backend for Lexmark X1100/X1200 Series scanners
</PRE>
<H2>DESCRIPTION</H2><PRE>
The <B>sane-lexmark</B> 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 <B>beta-quality</B> 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 <B><A HREF="scanimage.1.html">scanimage(1)</A></B> or through GUI elements in
<B><A HREF="xscanimage.1.html">xscanimage(1)</A></B> or <B><A HREF="xsane.1.html">xsane(1)</A></B>.
If you notice any strange behavior, please report to the backend main-
tainer or to the SANE mailing list.
Valid command line options and their syntax can be listed by using
scanimage --help -d lexmark:usb:&lt;usb port&gt;
<B>Scan</B> <B>Mode</B> <B>Options</B>
<B>--mode</B> selects the basic mode of operation of the scanner. Valid
choices are <I>Color</I>, <I>Gray</I> and <I>Lineart</I>. The default mode is <I>Color</I>.
The <I>Lineart</I> mode is black and white only (1 bit). <I>Gray</I> mode
will produce 256 levels of gray (8 bits). <I>Color</I> mode allows for
over 16 million different colors produced from 24 bits of color
information.
<B>--resolution</B>
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)
<B>--preview</B>
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".
<B>--threshold</B>
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 de-
fault value of the threshold option is 50.

<H2>CONFIGURATION FILE</H2><PRE>
The configuration file <I>/usr/local/etc/sane.d/lexmark.conf</I> contains only
the usb device id (eg usb 0x043d 0x007c).
</PRE>
<H2>FILES</H2><PRE>
<I>/usr/local/lib/sane/libsane-lexmark.a</I>
The static library implementing this backend.
<I>/usr/local/lib/sane/libsane-lexmark.so</I>
The shared library implementing this backend (present on systems
that support dynamic loading).
</PRE>
<H2>ENVIRONMENT</H2><PRE>
<B>SANE_DEBUG_LEXMARK</B>
If the library was compiled with debug support enabled, this en-
vironment 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.
<B>SANE_DEBUG_LEXMARK_LOW</B>
Provides debug output for low level Lexmark functions.
</PRE>
<H2>LIMITATIONS</H2><PRE>
The windows TWAIN driver has many more options than this SANE backend.
However they are only software adjustments. This backend only imple-
ments 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.

<H2>BUGS</H2><PRE>
