Abstract
In order to overcome inefficient power dissipation in parasitic resistances and to provide economies in the power supply, a higher resistance value segmented heater resistor is employed in a thermal inkjet printhead. A production tolerance early failure mechanism is avoided with the use of a cut introduced into the conductive shorting bar coupling the segments of the heater resistor.
