The printhead controller is configured to modify operation of at least some of the nozzles in response to the temperature rising above a first threshold. The printhead module is a thermal inkjet printhead module and each of the nozzles includes a thermal ink ejection mechanism. Each thermal sensor comprises at least part of one of the thermal inkjet mechanisms.
