Abstract
An inkjet printhead has a plurality of nozzle arrangements. Each nozzle arrangement comprises an ink chamber having an ink supply channel and an ink ejection port; an ink spreading prevention rim provided around and spaced apart from the ink ejection port to define a pit between the ink ejection port and the ink spreading prevention rim; and a thermal actuator mechanism configured to operatively eject ink from the chamber via the ejection port. The plurality of nozzle arrangement are grouped into pods, each pod having two rows of nozzle arrangements spatially staggered with respect to each other.
