Yes, of course, but the first step in assessing any sort of camera malfunction is to establish if it is in sound basic condition and set up according to the maker's instructions. I'm not saying a pressure plate set to 35mm would necessarily result in scratches to the emulsion but it's not the point, (in the first instance). Because if it's not set to 6x6, it raises an issue for investigation. If it is correctly set it can be eliminated from the list of things to check—it's as simple as that.
