Abstract (en)
The present invention is a melt-on-demand printhead (20) that keeps the entire solid ink supply (24) at room temperature until it receives a print command, then it rapidly applies a distributed heat over a large surface area of the ink supply (24) without the aid of thermal conductors to transport the heat. A portion of the solid ink (24) melts and travels into the drop ejector (28) that expels an ink drop to the medium within seconds of when the printhead (20) received a print command. The melt-on-demand thermal ink jet printhead (20) has a solid ink supply (24), a drop ejector (28) located near the solid ink supply (24), and a thin-film solid ink heater (38) located near a large surface area of the solid ink supply (24) that it rapidly heats.
