More Information
Summary:A printhead includes a liquid manifold. A filter is in fluid communication with the liquid manifold. A nozzle plate includes a length and an array of nozzles extending along the length of the nozzle plate. A liquid chamber is positioned between the nozzle plate and the filter. The liquid chamber is in fluid communication with the array of nozzles and the filter and includes a width that is substantially perpendicular to the length of the nozzle plate. The liquid chamber includes a structure that is spaced apart from the nozzle plate and in contact with the filter. The structure spans the width of the liquid chamber and includes a plurality of flow through channels. A liquid source provides a liquid through the manifold, the filter, the liquid chamber under pressure sufficient to jet individual streams of the liquid from the array of nozzles.
