Sensorless function monitoring of drying through plausibility monitoring of power consumption

摘要

A method for monitoring a drying unit (130) of an ink-jet printing system (100) or for determining the drying state of a recording medium (120) is described. The method (400) recognizes from the course (310) of the electrical power consumption of a heating saddle (202) of the drying unit (130) whether or not the recording medium (120) rests on the surface of the heating saddle (202).
