(...and after 2 hours I finally found my screwdriver :)

Now it looks like the unit moves against the gear on the step motor when
|
|
<BR>
|
|
I scan through the net backend.
|
|
<BR>
|
|
<P>Ah, and there's another problem:
|
|
<BR>
|
|
I only can do one scan through the net backend with xscanimage. Any
|
|
<BR>
|
|
attempt to do a second scan results either in an error message
|
|
<BR>
|
|
<P>Failed to start scanner: Error during device IO
|
