Abstract
Electrostatic attraction serves as a glue between a piezoelectric actuator and a flexible wall of the fluid chamber. A single actuator which can be shared among channels, provides the effort to drive ink out of the nozzle. The electrostatic field can be switched on and off; and so, individual channels are selectively clamped to the actuator only when those channels are to eject drops.
