Zusammenfassung:Apparatuses useful for printing and methods of treating marking material on media are provided. An exemplary embodiment of the apparatuses includes a first member including a first outer surface; and a roll including a second outer surface forming a nip with the first outer surface. The second outer surface includes an inner portion having first and second axially-spaced edges, a roughened first high-friction surface axially outward from the first edge and a roughened second high-friction surface axially outward from the second edge. The first and second high-friction surfaces extend circumferentially around the roll and have a higher roughness than the inner portion. The inner portion and the first and second high-friction surfaces contact the first outer surface at the nip, and the first and second high-friction surfaces lie outside of a media path through the nip.
