Method of controlling an operating temperature of a printhead in an ink jet cartridge assembly |
摘要 |
The invention is directed to a method of controlling an operating temperature of a printhead in an ink jet cartridge assembly, with the printhead having a plurality of ink emitting orifices and a plurality of corresponding heater elements. A cooling rate of the printhead which occurs during inoperation of the heater elements is established. A heating rate of the printhead which occurs as a result of firing at least one of the heater elements is determined. A period of time is set. A variable representing a control temperature of the printhead is calculated, dependent upon each of the cooling rate and the heating rate during the period of time. The operating temperature of the printhead is controlled, dependent upon the value of the variable representing the control temperature.
