I had a Pro 8110s with the same type pattern of spots. It was caused by the ITB transfer roller.

In addition to the belt and 4 image transfer (D0746158) rollers that you've already changed, I would suggest the opposed roller (D0746110) as well. This is the ITB bias roller at the very bottom of the ITB assembly that is directly opposite the PTR. All five rollers are on an 1800K PM cycle.
