1. A liquid ejecting device comprising:
a head including a plurality of nozzles;
a cap;
a moving mechanism 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 plurality of nozzles; and
a controller configured to perform:
first switching the cap from the capping state to the non-capping state by driving the moving mechanism;
after completing the first switching, second switching the cap from the non-capping state to the capping state by driving the moving mechanism;
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 in the first switching until a timing at which the cap is switched back to the capping state in the second switching;
after completing the second switching, vibrating meniscus of liquid in the plurality of nozzles without ejecting the liquid from the plurality of nozzles for the non-ejection drive time set in the setting while maintaining the cap in the capping state; and
after completing the vibrating meniscus of the liquid in the plurality of nozzles, maintaining the cap in the capping state without vibrating the meniscus until receiving a recording command.
