US Patent 7748811 Liquid jet apparatus

A liquid jet apparatus includes a liquid jet head and a driving signal generating circuit. The driving signal generating circuit generates driving signals including ejection pulses to control the ejection of liquid droplets. A first driving signal is supplied to a first actuator unit and a second driving signal is supplied to a second actuator unit. A first ejection pulse is generated, followed by a second ejection pulse generated after a delay time of Δt. The delay time Δt is set within a range that allows a liquid droplet to be ejected with reduced misting and reduced deviation from a predetermined path.
