摘要： A method for operating a thermal ink jet printer including a printhead having ink firing heater resistors responsive to pulses provided to the printhead. Warming voltage pulses are applied to the printhead to warm the printhead to a temperature that is at least as high as a temperature that would be produced pursuant to ink firing pulses of a predetermined voltage, a predetermined pulse width, and a predetermined pulse frequency. A continuous series of ink firing pulses are then applied to the printhead, starting with a pulse energy substantially equal to the predetermined reference pulse energy and a pulse frequency equal to the predetermined pulse frequency, and then incrementally decreasing the pulse energy of the ink firing pulses. The temperature of the printhead is repeatedly sampled while the ink firing pulses are applied to the ink firing resistors to produce a set of temperature samples respectively associated with the decreasing pulse energies. A thermal turn on energy is determined from the temperature samples, and the printhead is operated at a pulse energy that is greater than the thermal turn on energy and in a range that provides a desired print quality while avoiding premature failure of the heater resistors.
摘要翻译： 一种用于操作热喷墨打印机的方法，其包括响应于提供给打印头的脉冲的具有喷墨加热器电阻器的打印头。 将加热的电压脉冲施加到打印头以将打印头加热至至少与根据预定电压，预定脉冲宽度和预定脉冲频率的墨点火脉冲产生的温度一样高的温度。 然后将连续的一系列喷墨脉冲施加到打印头，以基本上等于预定参考脉冲能量的脉冲能量和等于预定脉冲频率的脉冲频率开始，然后递增地减小墨点火脉冲的脉冲能量 。 打印头的温度被重复地采样，同时将油墨点火脉冲施加到油墨点火电阻器以产生分别与减小的脉冲能量相关联的一组温度样本。 从温度样品确定热打开能量，并且打印头以大于热打开能量的脉冲能量和在提供期望打印质量的范围内操作打印头，同时避免加热器电阻器的过早故障。
