I´ve got an UMAX Astra 1220S on an Adaptec 2940.<br>
Technicaly it seems to work.<br>
<p>
Now I´d like to brush up this little XEROX-Script that comes with SANE.<br>
<p>
How can I lower the sensitivity of the scanner while using scanimage ?<br>
The results I get in Grey-Mode tend to be a little to dark. It works out<br>
every shade there is on the paper. It even looks through the paper and<br>
scans stuff that you couldnt see with bare eye under normal conditions.<br>
Textmarker is read as black, too. This is obviously not very helpful.<br>
=8-}<br>
The Windows-Copy-Tool has a threshold-switch that handles this problem.<br>
Is there anything like that in ScanImage, too ?<br>
<p>
ScanImage stops every 2-3 inches while scanning. XScanImage runs w/o<br>
stops.<br>
How can I speed up scanimage ?<br>
I have increased the scsi-buffer in the scsi-headerfile before compiling<br>
the kernel and sane.<br>
<p>
