NAME
sane-teco2 - SANE backend for TECO / RELISYS scanners
DESCRIPTION
The sane-teco2 library implements a SANE (Scanner Access Now Easy)
backend that provides access to some TECO SCSI flatbed scanners. This
backend should be considered beta-quality software! TECO scanners are
sold under various brands like Relisys, Piotech, TRUST. This backend
may or may not support yours.
The scanners that should work with this backend are:
Vendor Model TECO model status
---------------------- -------------- -----------
Primax Jewel 4800 VM356A tested
Primax Profi 9600 VM6575 tested
Primax Profi 19200 VM6586 tested
Relisys APOLLO Express 3 VM356A tested
Relisys APOLLO Express 6 VM6565 tested
Relisys APOLLO Express 12 ? untested
Relisys AVEC II S3 VM3564 tested
Relisys AVEC Super 3 VM3575 tested
Relisys SCORPIO Pro VM6575 tested
Relisys SCORPIO Pro-S VM6586 tested
Relisys SCORPIO Super 3 VM3575 tested
For all these scanners, black&white and grayscale mode work well. How-
ever, most of them do not support more than a handful of resolutions in
color mode. See the backend home page (under AUTHOR) for the exact sta-
tus of each scanner.
Note that the untested scanner will not be directly supported. You
should contact the author for that.
The TECO VM number can usually be found at the back of the scanner. It
is also part of the FCC ID.
The options the backend supports can either be selected through command
line options to programs like scanimage or through GUI elements in
xscanimage or xsane.
If you have any success with a scanner not listed here, or if you have
any strange behavior, please report to the backend maintainer or to the
SANE mailing list.
Valid command line options and their syntax can be listed by using
scanimage --help -d teco2
Scan Mode
--mode selects the basic mode of operation of the scanner valid choices
are Black & White , Grayscale and Color The Black & White mode
is black and white only (1 bit). Grayscale will produce 256 lev-
els of gray (8 bits). Color will produce a 24 bits color image.
--resolution
selects the resolution for a scan. The scanner can do all reso-
lutions between 1 and 600, in increments of 1.
Geometry options
-l -t -x -y
control the scan area: -l sets the top left x coordinate, -t the
top left y coordinate, -x selects the width and -y the height of
the scan area. All parameters are specified in millimeters by
default.
Enhancement options
--custom-gamma
(color mode only) allows the user to specify a gamma table (see
the next 3 parameters).
--red-gamma-table
(color mode only) can be used to download a user defined gamma
table for the red channel. The table must be 256 bytes long.
--green-gamma-table
(color mode only) can be used to download a user defined gamma
table for the green channel. The table must be 256 bytes long.
--blue-gamma-table
(color mode only) can be used to download a user defined gamma
table for the blue channel. The table must be 256 bytes long.
--preview
requests a preview scan. The resolution used for that scan is 22
dpi and the scan area is the maximum allowed. The scan mode is
user selected. The default is "no".
CONFIGURATION FILE
The configuration file /usr/local/etc/sane.d/teco2.conf supports only
one information: the device name to use (eg /dev/scanner).
FILES
/usr/local/lib/sane/libsane-teco2.a
The static library implementing this backend.
/usr/local/lib/sane/libsane-teco2.so
The shared library implementing this backend (present on systems
that support dynamic loading).
ENVIRONMENT
SANE_DEBUG_TECO2
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.
SANE_TECO2_CAL_ALGO
Either 0 or 1. Selects the algorithm for the calibration. A
value of 1 seems to give better scans on the VM3575. Feedback on
it is welcome.
LIMITATIONS
The windows TWAIN driver has many more options than this SANE backend.
However they are only software adjustments. This backend only imple-
ments what the scanner can support.
BUGS
Plenty. Parts of this backend are still under development.
