SANE Scanner Access Now Easy sane-matsushita(5)
NAME
sane-matsushita - SANE backend for Panasonic KV-S high
speed scanners
DESCRIPTION
The sane-matsushita library implements a SANE (Scanner
Access Now Easy) backend that provides access to some Pana-
sonic KV-S high speed scanners. This backend is stable.
At present, the following scanners are known to work with
this backend:
Product id
--------------
KV-S25
KV-S25D
KV-S55EX (*)
KV-S2025C (*)
KV-S2045C (*)
KV-S2065L (*)
(*) WARNING: None of the advanced options of these scanners
are available (ie no color, no high resolution, no automatic
cropping). Basically, the driver does no more than what it
does for the KV-S25. I don't have access to such scanners,
and thus cannot add these options.
Other Panasonic high speed scanners may or may not work with
that backend.
Valid command line options and their syntax can be listed by
using
scanimage --help -d matsushita
Scan Mode
--mode
selects the basic mode of operation of the scanner.
--resolution
selects the resolution for a scan. Each model supports
all or a subset of these resolutions: 100, 150, 200,
240, 300, 360, 400.
--duplex
indicates whether to scan both side of the sheet.
--feeder-mode
selects the number of pages to scan (one or until the
tray is empty).

Geometry
--paper-size A4...LegalLetter [A4]
options selects the area to scan. It adjust the -l -t
-x -y options accordingly. It does not need to be the
real size of the paper.
-l -t -x -y
control the scan area: -l sets the top left x coordi-
nate, -t the top left y coordinate, -x selects the
width and -y the height of the scan area. All parame-
ters are specified in millimeters. It is possible to
use the option --paper-size instead.
Enhancement
--brightness
controls the brightness of the acquired image. The
value varies from 1 to 255, or less, depending on the
scanner model.
--contrast
controls the contrast of the acquired image. Some
models do not support that option.
--automatic-threshold
automatically sets brightness, contrast, white level,
gamma, noise reduction and image emphasis. These
options are not available when automatic-threshold is
in use.
--halftone-pattern
option sets the tonal gradation for the halftone mode.
Pattern downloading is not implemented by the backend.
--autoseparation
provides automatic separation of text and images.
--white-level
option indicate the source of the white base.
--noise-reduction
reduces the isolated dot noise. This option is not sup-
ported by all scanners.
--image-emphasis
option sets the image emphasis. Some selection are not
available on all scanners.

--gamma
options set the gamma curve. It is only valid for Gray
modes, and is not available on all scanners. Gamma
downloading is not implemented by the backend.
CONFIGURATION FILE
The configuration file /etc/sane.d/matsushita.conf supports
the device name to use (eg /dev/scanner) and the SCSI option
to auto-detect the scanners supported.
FILES
/usr/lib/sane/libsane-matsushita.a
The static library implementing this backend.
/usr/lib/sane/libsane-matsushita.so
The shared library implementing this backend (present
on systems that support dynamic loading).
ENVIRONMENT
SANEDEBUGMATSUSHITA
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.
LIMITATIONS
Memory in the KV-S 25
The KV-S 25 has not enough internal memory to scan a
whole A4 page in duplex mode at high resolution. The
frontend will return a memory error in that case.
Apparently, the KV-S 25D has not that problem.
Pattern and gamma downloading
The scanner, with the proper firmware, can download a
halftone pattern and a gamma table. This is not imple-
mented.
Sub-areas
The scanner can support up to 3 sub-areas on each side
to define some more precise enhancement options. This
is not implemented.
Duplex mode
The backend does not support the setting of different
sane-backends 1.0Last change: February 11th, 2004 3
SANE Scanner Access Now Easy sane-matsushita(5)
options for each side. The scan will occur with the
same options (halftone pattern, brightness, image
emphasis) for both sides.
SCANING EXAMPLE
To date, the only frontend capable of using this scanner at
full speed is scanadf.
A scanadf command line would be:
scanadf -d matsushita --output-file scan%04d.pbm --start-
count 0 --duplex --resolution 300 --feeder-mode="All pages"
--paper-size="A4"
BUGS
None known.
