Abstract
This bubblejet device has integrated into it a number of heater resistors and a temperature sensor which operate in conjunction with a temperature regulating circuit to heat the chip to its optimum operating temperature within seconds of turn-on, and thereafter maintain that temperature regardless of local temperature variations. The precise temperature regulation of the array improves print quality.
