ABSTRACT:
An image forming apparatus defined by two flat, linear surface plates and two belts independently routed outside one of the two flat linear surface plates using a combination of rollers providing a stiff, linear, no-friction plane scalable in dimension to form the linear nip zone. The linear nip zone is further defined having and entrance defined by entrance rollers operating within each of the two belts and an exit defined by exit rollers operating within each of the two belts. Force loading devices associated with each of the two flat linear surface plates provide a load required for the two flat linear surface plates to enable the linear nip zone to achieve proper image performance. At least one heater roller can be associated with each of the two belts for providing heat directly to a surface the two belts that will directly contact paper processed through the linear nip zone.
