摘要： A printhead IC is provided having an ejection nozzle having a heater for heating printing fluid, and drive circuitry for generating print pulses and maintenance pulses for driving the heater of the ejection nozzle. The maintenance pulses have a series of sub-ejection pulses preceding a de-clog pulse. The print signals are generated to heat the heater to form a first vapor bubble in printing fluid that causes ejection of the printing fluid from the nozzle. The de-clog pulse is generated to have lower power and longer duration than the print pulses so as to heat the heaters to form a second vapor bubble in the printing fluid which does not cause ejection. The sub-ejection pulses are generated to have lower power than the print pulses and shorter duration than the de-clog pulse so as to heat the heater without sufficient energy to nucleate a vapor bubble in the printing fluid.

摘要： A printhead IC is provided which has an array of nozzles, drive circuitry for receiving print data and sending drive pulses of electrical energy to the array of nozzles in accordance with the print data, and a temperature sensor connected to the drive circuitry to adjust the drive pulse profile in response to the temperature sensor output. During use, the temperature sensor can be de-activated after a period of use. The drive circuitry sets the duration of the pulse profile to a sub ejection value for any of the nozzles in the row that are not to eject a drop during that firing sequence.
