Abstract:
A liquid discharge apparatus includes a liquid chamber communicating with a nozzle that discharges liquid; a capacity changer that changes a capacity of the chamber; an inflow path connected to the chamber allowing the liquid to enter the chamber; an outflow path connected to the liquid chamber allowing the liquid to exit the chamber; a first resistance changer changing a flow resistance of the inflow path; a second resistance changer changing a flow resistance of the outflow path; and a controller controlling the capacity changer, the first resistance changer, and the second resistance changer. The controller allows the nozzle to discharge the liquid by increasing the flow resistance of the inflow and outflow paths, increasing the capacity of the chamber, and then, while the flow resistance of the inflow and outflow paths remain increased, decreasing the capacity of the chamber.
