rotated scan interpretation
Somehow 2 scans in my exam were rotated by zesje. I could not find the scanned document itself quickly (I would have to go through 100s of pages to do this), but I can't imagine that this problem occurred in the scanner.
There were also a dozen or so cases where the page was ill-centered, due to a downward shift; but this is less problematic.
I removed the personally identifying information.
