Abstract

A novel thermal ink jet printhead and related methods of operation are described. Methods of manufacture of the printhead wherein multiple heater resistors (18,20) are connected in series between a source of ink supply (10) and an output ink ejection orifice (24). A primary heater resistor (20) is located in an ink ejection chamber (16) and adjacent an output ink ejection orifice (24). This resistor (20) propels ink away from the printhead, whereas another heater resistor (18) (or resistors) is removed from the primary heater resistor (20) and is located in an adjacent ink injection chamber (14), and is operative to inject ink toward the primary heater resistor (20). In this manner, ink ejection operational frequency is increased and cavitational wear on the heater resistors (20) is minimized. Simultaneously, hydrodynamic back pressure in the ink ejection chamber (16) is reduced, and control over ink drop size and viscosity is improved.
