摘要： A printhead IC is provided having an ejection nozzle, drive circuitry for generating drive signals for driving the ejection nozzle, and a temperature sensor connected to the drive circuitry. The drive circuitry adjusts the drive signals in response to output of the temperature sensor so as to generate the drive signals as print signals and de-clog signals. The de-clog signals have a longer duration than the print signals.
