Abstract:
1. A recording apparatus comprising: a channel unit comprising a pressure chamber configured to store a liquid to be ejected, and nozzles configured to eject the liquid; a reservoir unit connected to the channel unit and comprising a supply port to which the liquid is supplied from an outside, a drain port from which the liquid is drained to the outside, a supply channel communicating with the channel unit, and a drainage channel branching off from the supply channel and communicating with the outside via the drain port; a plurality of actuators configured to apply pressure to the liquid in the pressure chamber; a meniscus vibrator configured to drive the actuators to vibrate meniscus produced in the nozzles without causing liquid droplets to be ejected therefrom when the liquid supplied from the supply port is being drained from the drain port after traveling through the supply channel and the drainage channel; a drain valve configured to open and close the drain port; a pump configured to drain the liquid from the drain port when the drain port is opened by the drain valve; a temperature detector configured to detect the temperature of the liquid; and a pump controller configured to control the pump such that a flow rate of the liquid drained from the drain port to the outside per unit time is reduced as the temperature detected by the temperature detector increases.
