Scan-result is diagonal and in stripes


When I scan with grayscale I get what you see on page 2 of the picture. This is how it should look like.
When I then change in settings to black-white and do not change anything else, I get what you see on page 1 of the picture. It’s completely wrong.

It’s the same in …
When I try Paperwork 2.1.1 (Flatpack)
When I try paperwork 2.0.2
(HP printer)

Is there something I can do?

Thank you.
