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:

   Vendor Model           TECO model      status
----------------------  --------------  -----------
  Relisys AVEC 2400        VM3520        tested

  Relisys RELI DS6         VM3420        untested  
  Dextra  DF-600P          VM3510        tested
  Dextra  DF-4830T         VM4542        untested
  Dextra  DF-1200T+        VM3530+       untested
  Dextra  DF-9624          VM6530+       untested

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 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 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 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 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 information: 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 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

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

None known.
