Abstract: A liquid ejecting device includes a head, a cap, a moving mechanism and a controller. The moving mechanism is configured to move the head and the cap relative to each other to switch the cap between a capping state in which the cap is in contact with the head and covers the plurality of nozzles and a non-capping state in which the cap is separated from the head and uncovers the same. The controller is configured to perform setting a non-ejection drive time based on an uncapped time duration which is a length of time from a timing at which the cap is switched to the non-capping state until a timing at which the cap is switched back to the capping state. The controller is configured to perform vibrating meniscus of liquid in the plurality of nozzles during the non-ejection drive time.
