摘要：
A printhead controller is provided for supplying dot data to a printhead module having a plurality of nozzles for expelling ink. The printhead module includes a plurality of thermal sensors. Each of the thermal sensors is configured to respond to a temperature at or adjacent at least one of the nozzles. 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.
