Abstract
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.
Claims17
An apparatus for heating a printing substance and/or toner, in an electrophotographic printer, having at least one resonator with at least one cavity for microwaves emitted by a microwave transmitter, microwave source, or microwave generator, which produces at least one standing microwave, and which has a gap through which printed matter is caused to move, said apparatus comprising:
- said resonator configured for power distribution of the resonator-applied microwave which is preset and adjusted for each application requirement, said power distribution as a function of position is divided substantially into three areas, two areas from the walls of the resonator to the middle, in which the power remains constant, and the area between them, which represents a curve having a curvature such that the power distribution is trapezoidal, and by the fact that the side steepness is adjusted or changed.
