Liquid ejecting apparatus and method of driving liquid ejecting head
Abstract:
A liquid ejecting apparatus includes a liquid ejecting head having a pressure generating chamber which communicates with a nozzle opening for discharging a liquid and a pressure generating unit which generates a pressure variation within the pressure generating chamber; and a driving unit that supplies the pressure generating unit with a driving signal having an inflation element in which the pressure generating chamber is inflated, a contraction element in which the pressure generating chamber is contracted to discharge a liquid from the nozzle opening, and a re-inflation element in which the pressure generating chamber is inflated during the contraction element, wherein the re-inflation element is initiated in a state that two different phases of vibration of the meniscus within the nozzle opening are not opposite to each other.
