Abstract
A device and a method for applying and fusing a toner image on a substrate is described. The device has at least one printing unit, a transport unit for transporting the substrate through a print area of the printing units and a fusing unit for fusing toner on the substrate. The transport unit has an endless transport belt which passes continuously around at least two rollers to form a transport side. The fusing unit is in a transport direction of the endless transport belt behind the at least one printing unit and has at least one microwave applicator arranged adjacently to the endless transport belt for introducing microwaves into the substrate while the latter is being transported through it. With the method, a substrate to be printed is held on an endless transport belt and moved thereon through a print area of at least one printing unit and then through a fusing unit. In the print area of the at least one printing unit, a toner image is applied to the substrate, and inside the fusing unit the toner image is fused on the substrate by heating up the toner image by use of microwaves.
