This file is a short description of the coolscan-backend for sane!
The sane-coolscan library implements a SANE backend that provides the
interface to the following Nikon Coolscan Film scanners: Nikon LS20,
LS30, LS1000, LS2000.
Even though the backend has worked for a number of people, there are
still some 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
The configuration file for this backend resides in
Its contents 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
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 have to set the permissions of that device, have a look at
SCSI ADAPTER TIPS
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:
The backend configuration file:
The static library implementing this backend:
The shared library implementing this backend:
/usr/lib/arch_triplet/sane/libsane-coolscan.so (present on sys-
tems that support dynamic loading)
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: SANE_DEBUG_COOLSCAN values
The gamma table is not implemented for the LS1000 yet.
The dust-removal is not working yet

The original version of the coolscan backend by Didier
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.
