I have not seen this mentioned, but has anyone else with a Versant 3100 noticed this? We had the 2100 before and I don't think it did this. You have to really look close with a loop to see it. Even the engine prints show this. Tech tells me that is just the way they are. Doesn't really affect the look of prints but there are times I do notice it if you compare a printed side with a unprinted side. Makes it look like the white point of the paper is slightly cooler.
