ABSTRACT:
Inkjet printers having a microelectromechanical printhead are liable to printing inconsistencies due to various factors such as variations in the processes used to manufacture the printhead, e.g. actuator width, and ink temperature. In order to maintain a relatively constant print consistency an inkjet printer is provided having a printhead from which emanate a number of feedback lines. Feedback signals indicating parameters such as as printhead temperature and actuator width and resistivity are conveyed to a processor that adjusts the duration of firing pulses delivered to the actuators in a compensatory manner.
