Abstract
A fusing apparatus for fixing images made from a liquid toner onto a substrate using an electrophotographic process, the apparatus including a first fusing station having first and second prefusing rollers, the second prefusing roller contacting the first prefusing roller to create a first nip area, wherein at least one of the prefusing rollers is heated to a temperature that provides a prefusing temperature within the first nip area, and a second fusing station spaced from the first fusing station and having first and second final fusing rollers, the second final fusing roller contacting the first final fusing roller to create a second nip area, wherein at least one of the final fusing rollers is heated to a temperature that provides a fusing temperature within the second nip area, wherein the fusing temperature of the second nip area is higher than the prefusing temperature of the first nip area.
