摘要

A printhead comprising a plurality of inkjet nozzle assemblies is provided. Each nozzle assembly comprises a nozzle chamber formed on a substrate. The nozzle chamber comprises a roof spaced apart from the substrate and sidewalls extending between the roof and the substrate. The nozzle chamber has an ink ejection opening defined in the roof, a first ink inlet defined in one of the sidewalls, and a second ink inlet defined in a floor of the nozzle chamber. Each ink inlet is in fluid communication with a common ink reservoir. The nozzle assembly further comprises an actuator for ejection of ink through the ink ejection opening.
