sane-epsonds - SANE backend for EPSON ESC/I-2 scanners
|
|
<A NAME="lbAC"> </A>
|
|
<H2>DESCRIPTION</H2>
|
|
|
|
The
|
|
<B>sane-epsonds</B>
|
|
|
|
library implements a SANE (Scanner Access Now Easy) backend that
|
|
provides access to Epson ESC/I-2 scanners.
|
|
<P>
|
|
|
|
Valid command line options and their syntax can be listed by using
|
|
<DL COMPACT><DT id="1"><DD>
|
|
scanimage --help -d epsonds
|
|
</DL>
|
|
|
|
Not all devices support all options.
|
|
<DL COMPACT>
|
|
<DT id="2"><I>Scan Mode</I>
|
|
|
|
<DD>
|
|
The
|
|
<I>--mode</I>
|
|
|
|
switch selects the basic mode of operation of the scanner. Valid choices
|
|
are Lineart, Gray and Color. The Lineart mode is black and white only,
|
|
Gray will produce 256 levels of gray or more depending on the scanner
|
|
and Color means 24 bit color mode or more depending on the scanner.
|
|
Some scanners will internally use 36 bit color, their external interface
|
|
however may only support 24 bits.
|
|
<P>
|
|
The
|
|
<I>--depth</I>
|
|
|
|
option selects the bit depth the scanner is using. This option is only
|
|
available for scanners that support more than one bit depth. Older
|
|
scanners will always transfer the image in 8bit mode. Newer scanners
|
|
allow one to select either 8 bits, 12 or 14 bits per color channel. For a
|
|
color scan this means an effective color depth of 36 or 42 bits over
|
|
all three channels. The valid choices depend on the scanner model.
|
|
<P>
|
|
The
|
|
<I>--resolution</I>
|
|
|
|
switch selects the resolution for a scan. Some EPSON scanners will scan in
|
|
any resolution between the lowest and highest possible value. The list
|
|
reported by the scanner can be displayed using the "--help -d epson"
|
|
parameters to scanimage.
|
|
<P>
|
|
The geometry options
|
|
<I>-l -t -x -y</I>
|
|
|
|
control the scan area: -l sets the top left x coordinate, -t the top
|
|
left y coordinate, -x selects the width and -y the height of the scan
|
|
area. All parameters are specified in millimeters.
|
|
<P>
|
|
The
|
|
<I>--source</I>
|
|
|
|
option selects the scan source. Valid options depend on the installed
|
|
options. The default is "Flatbed".
|
|
<P>
|
|
The
|
|
<I>--eject</I>
|
|
|
|
option ejects the sheet in the ADF.
|
|
<P>
|
|
The
|
|
<I>--adf-mode</I>
|
|
|
|
option select the ADF mode (simplex/duplex).
|
|

<H2>CONFIGURATION FILE</H2>
|
|
|
|
The configuration file @CONFIGDIR@/epsonds.conf specifies the device(s) that the
|
|
backend will use. Possible connection types are:
|
|
<DL COMPACT>
|
|
<DT id="3"><I>USB</I>
|
|
|
|
<DD>
|
|
For not automatically detected USB scanners, their VENDOR and PRODUCT ID can
|
|
be specified manually in the config file.
|
|
More information about valid syntax for USB devices can be found in <A HREF="/cgi-bin/man/man2html?5+sane-usb">sane-usb</A>(5).
|
|
<DT id="4"><I>Network (not yet supported)</I>
|
|
|
|
<DD>
|
|
Network scanners can be auto-discovered if
|
|
<I>autodiscovery</I>
|
|
|
|
is specified after
|
|
<I>net</I>
|
|
|
|
keyword. An IP address to connect to can also be used.
|
|

|
<DL COMPACT>
|
|
<DT id="5"><I>@LIBDIR@/libsane-epsonds.a</I>
|
|
|
|
<DD>
|
|
The static library implementing this backend.
|
|
<DT id="6"><I>@LIBDIR@/libsane-epsonds.so</I>
|
|
|
|
<DD>
|
|
The shared library implementing this backend (present on systems that
|
|
support dynamic loading).
|
|

<DL COMPACT>
|
|
<DT id="7"><B>SANE_DEBUG_EPSONDS</B>
|
|
|
|
<DD>
|
|
If the library was compiled with debug support enabled, this
|
|
environment variable controls the debug level for this backend. E.g.,
|
|
a value of 128 requests all debug output to be printed. Smaller
|
|
levels reduce verbosity. Values around 11-16 will usuallybe enough for
|
|
a bug report.
