<DIV><FONT face=Arial size=2>Hi ,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial><FONT size=2><EM> Does the scanner work ok otherwise?
I'm asking because it's labeled </EM>></FONT></FONT><I><FONT size=2><FONT
face=Arial> "untested" in our lists.</FONT><BR></FONT></I></DIV>
<DIV><FONT face=Arial size=2>Ya the scanner avision 830C which i m using works
fine with windows.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2><EM>Which backend version are you
using?</EM></FONT></DIV>
<DIV><EM><FONT face=Arial size=2></FONT></EM> </DIV>
<DIV>
<DIV><FONT face=Arial size=2>The backend version which i m using is 1.0.12,
which i think is the latest one.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial size=2>The backend does provide the setting for brightness
and i m giving the brightness as 50. Also i tried to test with gamma table, the
documentation says that if u give gamma-table = (yes) then it will use the
default gamma table. i tried this option but when i give this option then the
result was a 0bytes file. That is the scanning didnt worked at all. But i can
surely try to generate a gamma table and then try using it. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The command i m using for scanning is </FONT></DIV>
<DIV><FONT face=Arial size=2><STRONG>scanimage --brightness 50 --mode grayscale
--format Tiff > abc.tiff</STRONG></FONT></DIV>
<DIV><STRONG><FONT face=Arial size=2></FONT></STRONG> </DIV>
<DIV><STRONG><FONT face=Arial size=2></FONT></STRONG> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2><STRONG>I have one more doubt
:</STRONG></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have 4 versions of Avision scanners, they are
:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1. Avision 8000S</FONT></DIV>
<DIV><FONT face=Arial size=2>2. Avision 3200C</FONT></DIV>
<DIV><FONT face=Arial size=2>3. Avision 600U</FONT></DIV>
<DIV><FONT face=Arial size=2>4. Avision 820C</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>No where in the documentation i can found
that I can use ADF of these scanners. Is there any way that i can use
the ADF for these scanners????</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
