ABSTRACT:
High gloss is provided for multicolor images formed on opposite sides of a receiving sheet in a double pass system using a fuser having a smooth, soft pressure roller surface. Preferably, a thin elastomeric outer layer on the pressure roller has a shore .ANG. durometer less than 40 and a roughness average less than 40 microinches. When a second multicolor image is fused to a receiving sheet by contact with a fusing roller, the gloss of a first multicolor image on the opposite side of the receiving sheet that has already been fused is not reduced by contact with the pressure roller, but is, in fact, enhanced.
