NAME

6       sane-matsushita - SANE backend for Panasonic KV-SS high speed scanners
7

DESCRIPTION

9       The sane-matsushita library implements a SANE (Scanner Access Now Easy)
10       backend that provides access to some Panasonic KV-SS high  speed  scan‐
11       ners. This backend is stable.
12
13       At present, the following scanners are known to work with this backend:
14
15                Product id
16              --------------
17                 KV-SS25
18                 KV-SS25D
19                 KV-SS55EX (*)
20                 KV-S2025C (*)
21                 KV-S2045C (*)
22                 KV-S2065L (*)
23
24       (*)  WARNING: None of the advanced options of these scanners are avail‐
25       able (ie no color, no high resolution, no  automatic  cropping).  Basi‐
26       cally,  the  driver  does  no more than what it does for the KV-SS25. I
27       don't have access to such scanners, and thus cannot add these options.
28
29       Other Panasonic high speed scanners may or may not work with that back‐
30       end.
31
32       Valid command line options and their syntax can be listed by using
33              scanimage --help -d matsushita
34
35
36       Scan Mode
37
38
39       --mode selects the basic mode of operation of the scanner.
40
41       --resolution
42              selects  the resolution for a scan. Each model supports all or a
43              subset of these resolutions: 100, 150, 200, 240, 300, 360, 400.
44
45       --duplex
46              indicates whether to scan both side of the sheet.
47
48       --feeder-mode
49              selects the number of pages to scan (one or until  the  tray  is
50              empty).
51
52
53       Geometry
54
55
56       --paper-size A4|...|Legal|Letter [A4]
57              options  selects  the  area  to  scan. It adjust the -l -t -x -y
58              options accordingly. It does not need to be the real size of the
59              paper.
60
61
62       -l -t -x -y
63              control the scan area: -l sets the top left x coordinate, -t the
64              top left y coordinate, -x selects the width and -y the height of
65              the  scan  area. All parameters are specified in millimeters. It
66              is possible to use the option --paper-size instead.
67
68
69       Enhancement
70
71
72       --brightness
73              controls the brightness of the acquired image. The value  varies
74              from 1 to 255, or less, depending on the scanner model.
75
76       --contrast
77              controls  the contrast of the acquired image. Some models do not
78              support that option.
79
80       --automatic-threshold
81              automatically sets brightness,  contrast,  white  level,  gamma,
82              noise reduction and image emphasis. These options are not avail‐
83              able when automatic-threshold is in use.
84
85       --halftone-pattern
86              option sets the tonal gradation for the halftone  mode.  Pattern
87              downloading is not implemented by the backend.
88
89       --autoseparation
90              provides automatic separation of text and images.
91
92       --white-level
93              option indicate the source of the white base.
94
95       --noise-reduction
96              reduces  the isolated dot noise. This option is not supported by
97              all scanners.
98
99       --image-emphasis
100              option sets the image emphasis. Some selection are not available
101              on all scanners.
102
103       --gamma
104              options  set  the  gamma curve. It is only valid for Gray modes,
105              and is not available on all scanners. Gamma downloading  is  not
106              implemented by the backend.

CONFIGURATION FILE

111       The  configuration file /etc/sane.d/matsushita.conf supports the device
112       name to use (eg /dev/scanner) and the SCSI option  to  auto-detect  the
113       scanners supported.
114
115
116

FILES

118       /usr/lib*/sane/libsane-matsushita.a
119              The static library implementing this backend.
120
121       /usr/lib*/sane/libsane-matsushita.so
122              The shared library implementing this backend (present on systems
123              that support dynamic loading).
124
125
126

ENVIRONMENT

128       SANE_DEBUG_MATSUSHITA
129              If the library was compiled with  debug  support  enabled,  this
130              environment  variable controls the debug level for this backend.
131              E.g., a value of 128 requests all debug output  to  be  printed.
132              Smaller levels reduce verbosity.

135

LIMITATIONS

137       Memory in the KV-SS 25
138              The  KV-SS  25 has not enough internal memory to scan a whole A4
139              page in duplex mode at high resolution. The frontend will return
140              a  memory  error in that case. Apparently, the KV-SS 25D has not
141              that problem.
142
143       Pattern and gamma downloading
144              The scanner, with the proper firmware, can download  a  halftone
145              pattern and a gamma table. This is not implemented.
146
147       Sub-areas
148              The scanner can support up to 3 sub-areas on each side to define
149              some more precise enhancement options. This is not implemented.
150
151       Duplex mode
152              The backend does not support the setting  of  different  options
153              for  each  side.  The  scan  will  occur  with  the same options
154              (halftone pattern, brightness, image emphasis) for both sides.
155
156
157

SCANNING EXAMPLE

159       To date, the only frontend capable of using this scanner at full  speed
160       is scanadf.
161
162       A scanadf command line would be:
163
164       scanadf   -d  matsushita  --output-file  scan%04d.pbm  --start-count  0
165       --duplex --resolution 300 --feeder-mode="All pages" --paper-size="A4"
