Method of adjusting the duration of printing pulses |
摘要 |
The present invention relates to a method of printing using dots of ink discharged from nozzles to form the image. To ensure quality and efficiency of printing, a feed back mechanism from the printhead is used, to provide real time readings on various parameters of the printhead. These readings are compared to a pulse parameter table, to adjust the parameter of the pulse to ensure quality and efficiency of the printing. The temperature of the printhead is sensed to allow the timing of the firing pulses to be adjusted to take into consideration the viscosity of the ink. The amount of voltage available to the pulse actuator can be sensed so that the pulse width can be adjusted to compensate for a flat battery or high voltage source. The resistivity of the actuator heater can be sensed so as to adjust the pulse widths to maintain a constant energy irrespective of the heater resistivity.
