Abstract
A printhead chip for an ink jet printhead includes a substrate. A plurality of nozzle arrangements is positioned on the substrate. Each nozzle arrangement has a nozzle chamber structure that is positioned on the substrate to define a nozzle chamber. An ink ejection member is displaceable with respect to the nozzle chamber structure to eject ink from the nozzle chamber. Two actuators are operatively engaged with the ink ejection member to displace the ink ejection member. The actuators are configured and connected to the ink ejection member to impart substantially rectilinear movement to the ink ejection member.
