Abstract:
A printhead arrangement for a printer, the arrangement having a plurality of nozzle assemblies formed on a wafer substrate by means of micro-electromechanical (MEMS) techniques. Each assembly includes an ink chamber with at least one ink supply channel etched into the substrate, and a heater element suspended in the ink chamber. Each assembly also includes drive circuitry for driving said heater element, and a nozzle plate defining two ink ejection nozzles. The nozzle plate has gutter formations about each nozzle to collect ink run-off.
