ABSTRACT:
An inkjet nozzle with an elongate ink inlet channel at least 150 microns long. The channel defines a straight flow path of a length sufficient to provide enough viscous damping to prevent significant reverse flow of ink in the channel when an ink drop is ejected from the nozzle.This removes the need to form ink supply channels with complex geometries such as pinch points and baffles in order to have the required hydraulic resistance to reverse flow. The nozzle packing density on the printhead can be significantly increased if these complex geometries are not formed adjacent the chambers. The ink can be supplied from the ‘back’ surface of the wafer, thereby removing the need for ink feed channels beside the chambers. This provides more room for the power and print data to be connected to each nozzle along the front surface of the wafer.
