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 AVEC 2412	 VM3520+       untested
		Relisys AVEC 4800	 VM4530        untested
		Relisys AVEC 4816	 VM4530+       untested
		Relisys RELI 2400	 VM3530        untested
		Relisys RELI 2412	 VM3530+       tested
		Relisys RELI 2412	 VM3530+       untested
		Relisys RELI 4816	 VM4540        untested
		Relisys RELI 4830	 VM4542        tested
		Relisys RELI 9600	 VM6530        untested
		Relisys RELI 9612	 VM6530*       untested
		Relisys RELI 9624	 VM6530+       untested
		Relisys RELI 9630	 VM6540        untested
		Relisys RELI DS15	 VM3440        untested
		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  scan-
       ner, 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  behav-
       ior, 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 coordi-
	      nate, -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 parame-
	      ters).

       --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 /etc/sane.d/teco1.conf supports only one	information:  the  device
       name to use (eg /dev/scanner).

FILES
       /usr/lib/sane/libsane-teco1.a
	      The static library implementing this backend.

       /usr/lib/sane/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.
