sane-teco1(5) SANE Scanner Access Now Easy sane-teco1(5)
NAME
sane-teco1 - SANE backend for TECO / RELISYS scanners
DESCRIPTION
The sane-teco1 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:

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. "sane-find-scanner -v" will also show the
scsi inquiry, and if it is a TECO scanner, the name will be there too.
The options the backend supports can either be selected through command
line options to programs like scanimage or through GUI elements in xs-
canimage 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 teco1
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.
--dither
(Black & White only) select the dither mask to use. Possible
values are Line art , 2x2 , 3x3 , 4x4 bayer , 4x4 smooth , 8x8
bayer , 8x8 smooth , 8x8 horizontal and 8x8 vertical
--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 @CONFIGDIR@/teco1.conf supports only one infor-
mation: the device name to use (eg /dev/scanner).
FILES
@LIBDIR@/libsane-teco1.a
The static library implementing this backend.
@LIBDIR@/libsane-teco1.so
The shared library implementing this backend (present on systems
that support dynamic loading).
ENVIRONMENT
SANE_DEBUG_TECO1
If the library was compiled with debug support enabled, this en-
vironment 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
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
None known.
