Abstract:
An inkjet printhead having a fluidic chamber substrate, the fluidic chamber substrate having at least two droplet units provided in an array therein, the droplet units comprising: a fluidic chamber, a first fluidic port provided at a first surface of the fluidic chamber substrate, wherein the first fluidic port is in fluidic communication with the fluidic chamber, a nozzle formed in a nozzle layer provided at a second surface of the fluidic chamber substrate; and a vibration plate provided at the first surface of the fluidic chamber substrate, the vibration plate comprising an actuator for effecting pressure fluctuations within the fluidic chamber; and wherein the droplet units are arranged adjacent each other about an axis extending substantially in a width direction of the droplet units, wherein the first fluidic ports of the droplet units are staggered a first stagger offset distance from each other substantially in a length direction of the droplet units, and wherein a wiring layer extends over the first surface of the fluidic chamber substrate and between the first fluidic ports.
