sane-teco2(5) SANE Scanner Access Now Easy sane-teco2(5)NAMEsane-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. However, 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 status of each
scanner.
Note that the untested scanner will not be directly sup-
ported. 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 levels of
gray (8 bits). Color will produce a 24 bits color
image.
--resolution
selects the resolution for a scan. The scanner can
do all resolutions between 1 and 600, in increments
of 1.
Geometry options
-l -t -x -y
control the scan area: -l sets the top left x coor-
dinate, -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 maxi-
mum allowed. The scan mode is user selected. The
default is "no".
CONFIGURATION FILE
The configuration file /usr/freeware/etc/sane.d/teco2.conf
supports only one information: the device name to use (eg
/dev/scanner).
FILES
/usr/freeware/lib32/sane/libsane-teco2.a
The static library implementing this backend.
/usr/freeware/lib32/sane/libsane-teco2.so
The shared library implementing this backend (pre-
sent 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 cali-
bration. 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 implements what the scanner can support.
BUGS
Plenty. Parts of this backend are still under development.
