ABSTRACT:
An inkjet cartridge for use with a thermal inkjet printer includes a standpipe area and an entrained ink chamber that are connected in fluidic communication. The entrained ink chamber and standpipe area can be enclosed by a wall that can have a plurality of panels or facets. The inkjet cartridge also includes a duct or passage that is connected in fluidic communication to both the standpipe area and the entrained ink chamber, wherein the connection to the entrained ink chamber is operatively located above the standpipe area, thus enabling anomalous air bubbles to migrate from the standpipe area and into the entrained ink chamber.
