Abstract
A recording apparatus may include a channel unit including a pressure chamber configured to store a liquid, and nozzles. The recording apparatus may include a reservoir unit connected to the channel unit and including a supply port, a drain port, 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. The recording apparatus may include actuators configured to apply pressure to the liquid in the pressure chamber. The recording apparatus may include 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.
