ABOUT THIS FILE
This file is a short description of the coolscan-backend for sane!
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 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
#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.
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 dont 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
