sane-coolscan - SANE backend for Nikon film-scanners
This file is a short description of the coolscan-backend for sane!
library implements a SANE backend that provides the
interface to the following Nikon Coolscan Film scanners: Nikon LS20, LS30,
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 time.
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 sane-scsi.
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/local/lib/sane/libsane-coolscan.so (present on systems 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:
setenv SANE_DEBUG_COOLSCAN 8
The autofocus command does not work with some SCSI card/driver combinations
The gamma table is not implemented for the LS1000 yet.
The dust-removal is not working yet

not have started this)
