We're hoping to get a unit to review once they become available to reviewers. We'll check on that issue when feasible.
I've never seen wheel marks from a Canon Pro-1000. I checked through all the places I could observe with a high-powered flashlight and could not see any paper feed components that would leave pizza-wheel marks; but I can't see everything because much of the mechanism is inaccessible. As well, this printer uses a vacuum suction to stabilize the paper. How are you loading heavy papers? You should be using the rear manual feed slot and not the top sheet feeder.
