I notice this issue usually after changing a transfer belt.
The strange marks do not appear to be repeating.

The pattern does not appear to be repeating at all.
I've seen that and it's to the ITB unit. Do you change the entire unit or just the belt?
Have you checked if metal roollers under ITB Belt are not scratched? I have seen similar problem on 71xx and found scratched roller (probably someone tried clean it but damaged it instead).
