Abstract
A method and an apparatus for preventing damage inside a printing machine caused by the radiation of microwaves emanating from microwave mechanisms. Undesired effects of the microwave radiation are automatically detected and then limited by countermeasures. Special provision is made for detecting an electrical discharge, or smoldering or burning of a printing medium inside the microwave mechanism, and then initiating suitable countermeasures.
Claims30
A process for preventing damage inside a printing machine caused by microwave radiation emanating from microwave mechanisms, preferably microwave fuser mechanisms (3), comprising:
- detecting an undesired effect of the microwave radiation is automatically, and limiting said detected undesired effect by countermeasures.
An apparatus for the prevention of damage inside the printing machine caused by microwave radiation emanating from microwave mechanisms (3), preferably microwave fuser mechanisms, comprising:
- at least one detection mechanism for the detection of an undesired effect of microwave radiation and at least one mechanism for the execution of suitable countermeasures in response to detection of an undesired effect by said at least one detection mechanism.
