Try Stopping the print and check the transfer belt or swap a known good transfer belt and test with that.

If you have one of those microscopes that shows individual color dots, I would see what colors are being laid down. My thought is transfer unit, however I would also run U087 prints to show the individual colors.

Had a similar issue with a 5002i with spotty areas, and it needed the transfer unit values reset with U469 that someone didn't do after transfer unit replacement.
