Abstract
A heater for use in a phase change ink printhead reservoir is provided that includes a first insulating layer having at least one ink supply path opening, and a second insulating layer having at least one ink supply path opening that aligns with the at least one ink supply path opening in the first insulating layer. The heater includes a resistance heating trace arranged in a serpentine pattern between the first and the second insulating layers. The resistance heating trace is configured to receive electric current and to convert the electric current to heat. The resistance heating trace includes a trace ring for each ink supply path opening in the first and second insulating layers that forms a continuous perimeter around the corresponding ink supply path opening.
