Nozzle plate including permanently bonded fluid channel

Abstract

A printhead includes a nozzle membrane and a plurality of liquid chambers. Portions of the nozzle membrane define an array of nozzles. The nozzle array includes a length and each nozzle of the nozzle array includes an axis. Each of the plurality of liquid chambers is in fluid communication with a respective one of the nozzles of the nozzle array. Each of the plurality of liquid chambers includes a height dimension and a width dimension. The height dimension extends in a direction parallel to the axis of the respective nozzle. The width dimension extends in a direction along the length of the nozzle array. The height dimension and the width dimension have an aspect ratio of less than or equal to 9:1.
