<H2>DESCRIPTION</H2>
|
|
|
|
The
|
|
<B>sane-teco3</B>
|
|
|
|
library implements a SANE (Scanner Access Now Easy) backend that
|
|
provides access to some TECO SCSI flatbed scanners. This backend
|
|
should be considered
|
|
<B>alpha-quality</B>
|
|
|
|
software! TECO scanners are sold under
|
|
various brands like RELYSIS, PIOTECH, TRUST. This backend may or
|
|
may not support yours.
|
|
<P>
|
|
|

The scanners that should work with this backend are:

The TECO VM number can usually be found at the back of the
|
|
scanner. It is also part of the FCC ID.
|

<P>
|
|
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.

<P>

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.
|
|
<P>
|

Valid command line options and their syntax can be listed by using

color image.

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.

|
|
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.
