Abstract
A printhead integrated circuit including a MEMS layer having a plurality of nozzle assemblies and a CMOS layer having control circuitry. Each nozzle assembly includes a heater element for ejecting ink and sensing a temperature of the nozzle assembly. The control circuitry modifies operation of the heater elements in response to a sensed temperature exceeding a predetermined threshold.
