sane-coolscan(5) SANE Scanner Access Now Easy sane-coolscan(5) NAME sane-coolscan - SANE backend for Nikon film-scanners ABOUT THIS FILE This file is a short description of the coolscan backend for SANE. DESCRIPTION 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/dri- vers (AHA-1505/aha152x.o) and the autofocus command. You should con- sider this backend 'alpha' and be careful when using it the first time. CONFIGURATION The configuration file for this backend resides in /usr/lo- cal/etc/sane.d/coolscan.conf. Its content is a list of device names that correspond to Nikon Coolscan scanners. Empty lines and lines starting with a hash mark (#) are ig- nored. 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 sane-scsi(5). 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: http://an- dreas.rick.free.fr/sane/autofocus.html. FILES The backend configuration file: /usr/local/etc/sane.d/coolscan.conf The static library implementing this backend: /usr/local/lib/sane/libsane-coolscan.a The shared library implementing this backend: /usr/local/lib/sane/libsane-coolscan.so (present on systems that support dynamic loading) ENVIRONMENT SANE_DEBUG_COOLSCAN If the library was compiled with debug support enabled, this en- vironment 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 BUGS 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.

THANKS TO 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.
