sane\-lexmark \- SANE backend for Lexmark X1100/X1200 Series scanners
|
|
.SH "DESCRIPTION"
|
|
The
|
|
.B 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
|
|
.B beta-quality
|
|
software!
|

|

The scanners that should work with this backend are:

The options the backend supports can either be selected through
|
|
command line options to programs like
|
|
.BR scanimage (1)
|
|
or through GUI elements in
|
|
.BR xscanimage (1)
|
|
or
|
|
.BR xsane (1).

If you notice any strange behavior, please report to the backend
|
|
maintainer or to the SANE mailing list.

.B Scan Mode Options
|
|
|
|
.TP
|
|
.B \-\-mode
|
|
selects the basic mode of operation of the scanner. Valid choices are
|
|
.IR Color ,
|
|
.I Gray
|
|
and
|
|
.IR Lineart .
|
|
The default mode is
|
|
.IR Color .
|
|
The
|
|
.I Lineart
|
|
mode is black and white only (1 bit).
|
|
.I Gray
|
|
mode will produce 256 levels of gray (8 bits).
|
|
.I Color
|
|
mode allows for over 16 million different colors produced from 24
|
|
bits of color information.
|
|
|
|
.TP
|
|
.B \-\-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:

|

.B \-\-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".
|
|
|
|
.TP
|
|
.B \-\-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.
|
|
|
|
|
|
.SH "CONFIGURATION FILE"
|
|
The configuration file
|
|
.I @CONFIGDIR@/lexmark.conf
|
|
contains only the usb device id (eg usb 0x043d 0x007c).
|
|
|
|
|
|
.SH "FILES"
|
|
.TP
|
|
.I @LIBDIR@/libsane\-lexmark.a
|
|
The static library implementing this backend.
|
|
.TP
|
|
.I @LIBDIR@/libsane\-lexmark.so
|
|
The shared library implementing this backend (present on systems that
|
|
support dynamic loading).
|
|
|
|
|
|
.SH "ENVIRONMENT"
|
|
.TP
|
|
.B 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.
|
|
.TP
|
|
.B SANE_DEBUG_LEXMARK_LOW
|
|
Provides debug output for low level Lexmark functions.
|
|
|
|
.SH "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.

.SH "BUGS"
