Abstract (en)
In a inkjet print cartridge (10) ink flows from the reservoir around the edge of the silicon substrate (28) before being ejected out of the nozzles (72). During operation, warm thermal boundary layers of ink form adjacent the substrate (28) and dissolved gases in the thermal boundary layer of the ink form the bubbles. If the bubbles to grow larger than the diameter of subsequent ink passageways these bubbles choke the flow of ink to the vaporization chambers. This results in causing some of the nozzles (72) of the printhead (10) to become temporarily inoperable. The disclosure describes a method of avoiding such a malfunction in a liquid inkjet printing system by providing a bubble tolerant manifold design. <IMAGE>
