Title: Heater assembly including thermal fuse

Abstract: A heater assembly heats media substrate in a printing system prior to imprinting a desired image on the substrate. A plate member engages the substrate and communicates thermal energy thereto for the heating. A laminar assembly is adhered to the plate member and includes a trace pattern for converting electrical energy to the thermal energy. A thermal storage member is interposed between the plate member and the trace pattern for distributing thermal energy throughout the thermal storage member. Two thermal fuses are serially connected, one at each end of the trace pattern and disposed relative to the thermal storage member for detecting an undesired temperature increase in the laminar assembly sufficient for opening the fuses and electrically isolating the heater assembly against a consequential thermal run-away causing insulation degradation and an electrical short between the trace pattern and the plate member.
