ABSTRACT:
A thermal ink jet printhead with a plurality of newly designed bubble containment chambers for reducing a spattering effect which is the ejection of unwanted small aerosol type droplets after the ejection of an ink drop. The printhead has one or more ink channels each having an opening at one end, known as nozzle, and also having a bubble containment chamber for each channel at a predetermined distance from the nozzle. The new bubble containment chamber is designed to absorb or redirect undesired acoustic waves produced from the collapse of a bubble in the bubble containment chamber which in turn causes the ejection of unwanted small aerosol type droplets after the ejection of an ink drop. The bubble containment chamber of this design absorbs or redirects the acoustic energy by having four different kinds of wedges on its walls.
