Inkjet Pizza Wheel Star Wheel Marks

Wheel marks have been an issue on certain paper types for many years. They are mostly evident on semigloss and glossy surfaces, and especially on softer coatings. They also are more apparent in the darker colors.

There is no fix for the wheels, because they are at the end of the paper feed path and touch the paper regardless of how it's loaded into the machine. The up-side of the problem is that at viewing distance, and especially when framed, these small marks are all but invisible.
