Hi Ondrej,

horizontal stripes have nothing to do with calibration (vertical stripes could).

It looks like you have a hardware problem with your scanner.
The I/O errors are not good, but the bad noises you get when the scanner
produces stripes could mean that your scanner is not ok.

I never heard of such problems before.

Did you once forgot to open the transport-lock? That could have destroyed the
stepping motor/electronic.

Bye
Oliver
