Abstract

An inkjet printer that has an array of ink chambers, each with a nozzle, a droplet stem anchor and a thermal actuator. The thermal actuator generates a vapor bubble in the ink chamber to eject ink through the nozzle. The thermal actuator has a plurality of heater elements connected in parallel with a cross bracing structure extending between the heater elements. The cross bracing structure also providing the droplet stem anchor. During use, the vapor bubble generated by the thermal actuator grows until it vents to atmosphere through the nozzle and the ink ejected from the nozzle is attached to the droplet stem anchor by an ink stem until the stem breaks and the ejected ink forms a separate drop.
