A fuser stripper baffle exit minimizes differential gloss marks due to paper
contacting
the fuser exit baffle. Portions of paper that touch the baffle cool differently
than portions that don't, resulting in differential gloss in the paper path or
spanwise direction. The exit baffle contains a series of axial-direction steps
or plateaus in its upper surface, such that the highest step is nearest the fuser
roll, while the lowest plateau is furthest from the roll. This reduces the surface
area of the fuser stripper baffle exit that contacts the surface of the paper sheet
as the paper sheet is stripped from the fuser roll. The paper thus touches the
exit baffle for the minimum amount of time, thus minimizing the heat transfer to
the baffle. This minimizes differential cooling effects which, in turn, minimizes
differential gloss.
