sane-coolscan - SANE backend for Nikon film-scanners
</PRE>
<H2>ABOUT THIS FILE</H2><PRE>
This file is a short description of the coolscan backend for <B>SANE</B>.
</PRE>
<H2>DESCRIPTION</H2><PRE>
The <B>sane-coolscan</B> library implements a SANE backend that provides the
interface to the following Nikon Coolscan Film scanners: Nikon LS20,
LS30, LS1000, LS2000.
<B>Even</B> <B>though</B> <B>the</B> <B>backend</B> <B>has</B> <B>worked</B> <B>for</B> <B>a</B> <B>number</B> <B>of</B> <B>people,</B> <B>there</B> <B>are</B>
<B>still</B> <B>some</B> problems, especially in combination with some SCSI
card/drivers (AHA-1505/aha152x.o) and the autofocus command. You
should consider this backend 'alpha' and be careful when using it the
first time.
</PRE>
<H2>CONFIGURATION</H2><PRE>
The configuration file for this backend resides in
<I>/usr/local/etc/sane.d/coolscan.conf</I>.
Its content is a list of device names that correspond to Nikon Coolscan
scanners. Empty lines and lines starting with a hash mark (#) are
ignored. A sample configuration file is shown below:
#scsi Vendor Model Type
scsi Nikon * Scanner
/dev/scanner
The special device name must be a generic SCSI device or a symlink to
such a device. To find out to which device your scanner is assigned
and how you can set the permissions of that device, have a look at
<B><A HREF="sane-scsi.5.html">sane-scsi(5)</A></B>.
</PRE>
<H2>SCSI ADAPTER TIPS</H2><PRE>
Some SCSI-adapters and low-level SCSI drivers do not work correctly
with this backend and the Coolscan scanners. These systems hang when
the autofocus command is send to the Scanner. To see a list of which
card/driver combinations work or don't work have a look at:

</PRE>
<H2>FILES</H2><PRE>
The backend configuration file:
<I>/usr/local/etc/sane.d/coolscan.conf</I>
The static library implementing this backend:
<I>/usr/local/lib/sane/libsane-coolscan.a</I>
The shared library implementing this backend:
<I>/usr/local/lib/sane/libsane-coolscan.so</I> (present on systems that
support dynamic loading)
</PRE>
<H2>ENVIRONMENT</H2><PRE>
<B>SANE_DEBUG_COOLSCAN</B>
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.
Examples:
On bash:
export SANE_DEBUG_COOLSCAN=8
On csh:
setenv SANE_DEBUG_COOLSCAN 8
</PRE>
<H2>BUGS</H2><PRE>
The autofocus command does not work with some SCSI card/driver combina-
tions.
The gamma table is not implemented for the LS1000 yet.
The dust-removal is not working yet.

<H2>THANKS TO</H2><PRE>
Didier Carlier - For writing the original Coolscan backend (without it
I would not have started this).
Oliver Rauch - For adapting xsane so quickly to the infrared stuff.
All the other people working on SANE.
