ABSTRACT:
Methods and apparatus for performing addressable fusing and/or heating of a substrate undergoing xerographic processing are disclosed. The apparatus includes a fuser having an array of addressable heating elements in radiative communication with a substrate through a fuser roll or fuser belt. The array of addressable heating elements is operated to selectively heat portions of the substrate to achieve a desired effect on the substrate, such as changing its surface finish, or fusing unfused toner to the substrate. In the case of toner fusing, the array is operated such that substantially only an area covered by the unfused toner is heated. This eliminates the need for blanket fusing, and generally provides for greater flexibility in xerographically processing substrates. Apparatus and methods for performing two-sided selective fusing and/or heating are also disclosed.
