Method and unit for heating a printing support and/or toner

摘要

Method for fixing toner on a print medium such as paper using a microwave transmitter as a fixing device. The microwaves heat the print medium that causes melting of the toner. A toner is chosen that displays a large reduction in its elastic modulus when heating caused it to change from solid to liquid state. The ratio of liquid to solid elastic modulus is in the range 10<-5> to 10<-7>. An Independent claim is made for a device for heating print media and or toner, especially for fixing toner on a print medium using a microwave transmitter.
