In order to facilitate close packing of nozzle assemblies in a micro-electromechanical printhead, the assemblies are formed in a dumbbell shape with an ejection nozzle at one end and an actuator at the other. Rows of the nozzles are staggered so that the nozzles of one row nest between the ejection nozzles and actuators of nozzle assemblies of adjacent rows. In order to prevent mis-direction of ejected ink a nozzle guard is provided that includes a number of apertures located to correspond to each nozzle and to collimate ejected ink in use. |
