Abstract:
An inkjet printhead having an array of ink chambers is disclosed. Each ink chamber has a nozzle and a heater element for generating vapour bubbles to eject ink through the nozzle. The heater element has multiple current paths connected in parallel. Each current path has at least one portion with a reduced cross-section relative to the remainder of the current path. A cross bracing structure is also provided for connecting intermediate portions of the current paths.
