A heating device for heating at least one printing agent on a printing material which is moved along a transport path through said heating device includes a microwave applicator. A microwave absorber element is located in an outer perimeter of the microwave applicator. The microwave absorber element is an irradiation device that absorbs microwave radiation and emits electromagnetic radiation. The electromagnetic radiation can be applied to the printing agent or the printing material.

Microwave and electromagnetic printing agent heating device

A microwave fuser apparatus, for a reproduction apparatus, the microwave fuser apparatus having at least two microwave applicators, staggered relative to a receiver member transport path with an area of overlap, for applying microwave energy to a receiver member traveling on such transport path relative to the microwave applicators to have toner images fused thereto. The microwave fuser apparatus has at least one additional microwave applicator, located adjacent to the overlapping area between the at least two staggered microwave applicators that applies microwave energy to the receiver member. The at least one additional microwave applicator effectively maintains an elevated temperature of a receiver member.

Microwave fuser apparatus with overlaping heat applicators

A microwave fuser device for heating printing matter in a reproduction apparatus with microwave energy from a suitable microwave source. The microwave fuser device supplies microwave energy through the bottom of a multi-channel resonator including a gap to enable transport of printing matter therethrough. The device includes a power splitter having plural channels for dividing microwave energy from the microwave source between the channels of the multi-channel resonator. The power splitter has a mechanism to provide variable geometry of its plural channels, whereby the effective width of microwave energy from the resonator of the microwave fuser device can be matched to the width of such printed matter having an image fused thereto substantially preventing undesirable high loss of energy and low yield.

Power splitter for a microwave fuser of a reproduction apparatus

Heating a printing substance and/or toner, in an electrophotographic printer, with a standing microwave formed by at least one cavity resonator, with the printed matter being caused to move through the resonator gap. The power distribution of the microwave applied by the resonator is shaped and configured for specific application requirements.
