I don't want to join this ! I have 3 pass Scanner and this piece should be<br>
|
|
faster than 1 pass scanners ? Also I made different experiences under win95<br>
|
|
and twain. Sane (not the fastest scanning program under linux) is twice as fast<br>
|
|
as the twain driver. But I must say scanning with sane gets real fun after<br>
|
|
upgrading to 64 MB RAM ;-).<br>
|
|
<p>
|
|
Something different: Can somebody with a mustek 3-pass Scanner confirm or deny<br>
|
|
the problem with the "custom gamma table" option ? With this option selected<br>
|
|
the system freezes after starting the scan :-(.<br>
