Abstract:
A recording apparatus includes a recording head having a common liquid channel; plural pressure chambers; plural nozzles; plural individual liquid channels, each individual liquid channel extending from the common liquid channel via associated pressure chamber to associated nozzle; and plural actuators configured to impart a pressure to a liquid inside a respective one of the pressure chambers; and a control unit configured to drive the actuators; wherein the control unit comprises: an excessive state detection section configured to detect an excessive state in which a pressure difference between a liquid-side pressure and an air-side pressure at a meniscus formed at any one of the nozzles exceeds a threshold value when droplets are ejected from the nozzles, and a meniscus vibration section configured to drive the actuator associated with the nozzle that does not eject droplets such that the meniscus is subjected to vibration without ejecting the droplets.
