I'm very sorry, but I was only lucky for about 10 correct clean scans after my
above described reinstalling. Then the black line reappeared immediately after
scan before the correction by the software (repositioning). So the result was
always ok. But then I got two errors:
1) Warning running unpaper: out of deviation range - NO ROTATION
2) Error running unpaper: [image@0x561bb2222ea80] Using AVStream.codec to
pass codec parameters
to muxers is depreciated, use AVStream.codecpar unstead.
[image@0x561bb2222ea80] Encoder did not produce proper pts, making some
up.
The result of the scan was then shifted horizontally about 5 cm on my paper
towards the left and this didn't move even changing all various parameters. The
black line disappears but the page in not complete.
So for the moment I have to go back to Windows only for scanning.
There seems an error in unpaper, software applicated immediately after the
scan, because I can see the original scan with black line just before.
