摘要： Disclosed is a method for compensating a shift in an ON resistance of a transistor in a chip of a printhead of an inkjet printer. The method includes determining a value of a life indication parameter of the printhead and comparing the determined value of the life indication parameter of the printhead with at least one predetermined value of the life indication parameter. The at least one predetermined value of the life indication parameter of the printhead is stored in at least one of a memory of the inkjet printer and a memory of the chip of the printhead. Thereafter, a gate voltage input to the transistor is modified based on a difference between the determined value of the life indication parameter and the at least one predetermined value of the life indication parameter of the printhead for compensating the shift in the ON resistance of the transistor.

摘要： A thermal inkjet apparatus includes a printhead body, nozzles, ink cavities and ink supply lines. Heater resistors are in the cavities and a firing circuit is connected to provide firing pulses to the heater resistor and nucleate the ink so that it fires ink out of the nozzles. Each heater resistor is also connected to a warming circuit that supplies warming pulses, one warming pulse during each firing cycle, to warm the heater resistors but not nucleate the ink. The warming circuit includes current limiting ballast resistors to limit the current through the healer resistors and thereby prevent the warming pulse from nucleating the ink. Warming pulses and firing pulses are not generated during the same firing cycle for a particular heater resistor. One or more thermal sensors are disposed on the printhead body to sense the temperature and a control circuit responds to the sensors to generate warming pulses having desired widths to provide a desired level of warming. By wide range pulse width modulation of the warming pulse, the warming effect of the warming pulse may be increased or decreased as desired. Also the warming pulse may be completely eliminated, such as by pulse width modulating the pulse to have a zero duration.
