Claim:
An apparatus useful in printing, the apparatus comprising: a fuser having a fuser surface; at least one heat source configured to heat the fuser surface; a pressure roll having a pressure roll surface, a rotational axis, an inside paper path portion having an inside paper path diameter towards the middle of the pressure roll along the rotational axis and an outside paper path portion having an outside paper path diameter near at least one end of the pressure roll along the rotational axis, the pressure roll coupled to the fuser at a fuser nip, where-the fuser nip is configured to fuse marking material on a media sheet; and a pressure roll cooling device configured to cool at least one of the inside paper path portion and the outside paper path portion to selectively cause a pressure roll flare having a flare difference of substantially 0.3 mm to 0.9 mm, the flare difference being a difference between the inside paper path diameter and the outside paper path diameter of the pressure roll, wherein the flare difference is configured to provide wrinkle control of media sheets while limiting image smear of the marking material on the media sheets.
