Hi Ondrej,<br>
<p>
horizontal stripes have nothing to do with calibration (vertical stripes could).<br>
<p>
It looks like you have a hardware problem with your scanner.<br>
The I/O errors are not good, but the bad noises you get when the scanner<br>
produces stripes could mean that your scanner is not ok.<br>
<p>
I never heard of such problems before.<br>
<p>
Did you once forgot to open the transport-lock? That could have destroyed the<br>
stepping motor/electronic.<br>
<p>
Bye<br>
