ABOUT THIS FILE

10       This file is a short description of the coolscan-backend for sane!

DESCRIPTION

14       The  sane-coolscan  library implements a SANE backend that provides the
15       interface to the following Nikon Coolscan Film  scanners:  Nikon  LS20,
16       LS30, LS1000, LS2000.
17
18       Even  though  the  backend has worked for a number of people, there are
19       still  some  problems,  especially  in  combination  with   some   SCSI
20       card/drivers (AHA-1505/aha152x.o) and the autofocus command. You should
21       consider this backend 'alpha' and be careful when using  it  the  first
22       time.

CONFIGURATION

26       The    configuration    file    for    this    backend    resides    in
27       /etc/sane.d/coolscan.conf.
28
29       Its contents is a  list  of  device  names  that  correspond  to  Nikon
30       Coolscan  scanners. Empty lines and lines starting with a hash mark (#)
31       are ignored. A sample configuration file is shown below:
32
33        #scsi Vendor Model Type
34        scsi Nikon * Scanner
35        /dev/scanner
36
37       The special device name must be a generic SCSI device or a  symlink  to
38       such  a  device.   To find out to which device your scanner is assigned
39       and how you have to set the permissions of that device, have a look  at
40       sane-scsi.

SCSI ADAPTER TIPS

44       Some  SCSI-adapters  and  low-level  SCSI drivers do not work correctly
45       with this backend and the Coolscan scanners. These  systems  hang  when
46       the  autofocus  command is send to the Scanner.  To see a list of which
47       card/driver  combinations  work  or  dont  work   have   a   look   at:

FILES

54       The backend configuration file:
55              /etc/sane.d/coolscan.conf
56
57       The static library implementing this backend:
58              /usr/lib64/sane/libsane-coolscan.a
59
60       The shared library implementing this backend:
61              /usr/lib64/sane/libsane-coolscan.so  (present  on  systems  that
62              support dynamic loading)
63
64

ENVIRONMENT

66       SANE_DEBUG_COOLSCAN
67              If the library was compiled with  debug  support  enabled,  this
68              environment  variable controls the debug level for this backend.
69              E.g., a value of 128 requests all debug output  to  be  printed.
70              Smaller levels reduce verbosity: SANE_DEBUG_COOLSCAN values
71
72              Examples:
73
74              on bash:
75              export SANE_DEBUG_COOLSCAN=8
76
77              on csh:
78              setenv SANE_DEBUG_COOLSCAN 8

BUGS

82       The autofocus command does not work with some SCSI card/driver combina‐
83       tions
84
85       The gamma table is not implemented for the LS1000 yet.
86
87       The dust-removal is not working yet

THANKS TO

101       Didier Carlier - For writing the original Coolscan backend (without  it
102       I would not have started this)
103
104       Oliver Rauch - For adapting xsane so quickly to the infrared stuff.
