Abstract:
A liquid discharging apparatus includes a liquid discharging head having an actuator, a nozzle-formed surface on which a nozzle opens and discharging liquid from the nozzle by activating the actuator, and an activation pulse generation circuit that generates an activation pulse for activating the actuator. The nozzle-formed surface has a liquid repellent film formed thereon. The activation pulse includes a first pull-in component that pulls a meniscus in the nozzle from an initial position of the meniscus, a first push-out component that pushes the meniscus that has been pulled, a second pull-in component that pulls the meniscus that has been pushed, and a second push-out component that pushes at least a portion of the meniscus that has been pulled again. The nozzle discharges a special-type liquid. The special-type liquid is a type of liquid that relatively tends to cause repellency of the liquid repellent film to deteriorate.
