Abstract
An inkjet printhead includes a plurality of nozzle chambers disposed on a substrate. Each nozzle chamber includes: a floor having an ink inlet defined therein; a roof having a nozzle aperture defined therein; sidewalls extending between the floor and the roof; and a heater element suspended in the nozzle chamber, the heater element being connected to corresponding electrodes so as to heat fluid within the nozzle chamber thereby forming a gas bubble in the fluid which causes ejection of fluid through the nozzle aperture. The ink inlet is laterally offset from the nozzle aperture and a plane of the heater is parallel with a plane of the roof.
