sane-sm3840 - SANE backend for Microtek scanners with SCAN08 USB chip
<A NAME="lbAC">&nbsp;</A>
<H2>DESCRIPTION</H2>
The
<B>sane-sm3840</B>
library implements a SANE (Scanner Access Now Easy) backend that
provides access to some Microtek scanners with the SCAN08
USB chip.
<P>
There exist backends for Microtek scanners with SCSI command set.
Refer to <A HREF="/cgi-bin/man/man2html?5+sane-microtek">sane-microtek</A>(5) and <A HREF="/cgi-bin/man/man2html?5+sane-microtek2">sane-microtek2</A>(5) for details.
<P>
There also exists a Microtek 3600 series driver, see <A HREF="/cgi-bin/man/man2html?5+sane-sm3600">sane-sm3600</A>(5) for
details.
<P>
At present, the following
scanners are known positively to work with this backend:

Vendor Product ID: Remark:
-------- -------------- -----------
Microtek ScanMaker 3840 All modes OK
Microtek ScanMaker 4800 All modes OK
</PRE>
</DL>
<P>
If you own a Microtek scanner with the SCAN08 chip other than the ones
listed above, it may or may not work with SANE. Feel free to contact the
backend author (<A HREF="mailto:earle@ziplabel.com">earle@ziplabel.com</A>) to report results with scanners not
on the list.

<A NAME="lbAD">&nbsp;</A>
<H2>FRONTEND OPTIONS</H2>
<P>
The following options are supported by the sm3840-driver:
<P>
<B>--mode color|gray|lineart|halftone</B>
<BR>
Color or grayscale mode.
<P>
<B>--resolution 150|300|600|1200</B>
<BR>
Pixels per inch for scans.
<P>
<B>--depth 8|16</B>
<BR>
Note that the least significant bits of 16bpp mode may be noise.
<P>
<B>--brightness 1..4096</B>
<BR>
Higher numbers increase brightness of returned image.
<P>
<B>--contrast 0.1..9.9</B>
<BR>
Larger numbers decrease contrast of returned image.
<P>
<B>--lamp-timeout 1..15</B>
<BR>
Time in minutes until the lamp is turned off after a scan.
<P>
<A NAME="lbAE">&nbsp;</A>
<H2>CONFIGURATION</H2>
This backend does not support a configuration file right now.
<P>
<A NAME="lbAF">&nbsp;</A>
<H2>FILES</H2>
<DL COMPACT>
<DT id="2"><I>@LIBDIR@/libsane-sm3840.a</I>
<DD>
The static library implementing this backend.
<DT id="3"><I>@LIBDIR@/libsane-sm3840.so</I>
<DD>
The shared library implementing this backend (present on systems that
support dynamic loading).
<P>
<P>
</DL>
<A NAME="lbAG">&nbsp;</A>
<H2>ENVIRONMENT</H2>
<DL COMPACT>
<DT id="4"><B>SANE_DEBUG_SM3840</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. To see error messages on stderr set
SANE_DEBUG_SM3840 to 1.
