Abstract
An inkjet printer includes a nozzle surface provided on a head and having a nozzle ejecting ink, first and second flow paths connected to the head, a bypass flow path connecting the first and second flow paths outside the head, a cap provided to be in contact with the nozzle surface, and a controller. The controller executes circulation of the ink through the first flow path, the head and the second flow path, in a liquid-contact state where a cleaning liquid supplied in the cap is contacted with the nozzle surface, at an end of last printing or when an elapsed time from last cleaning in the cap is within a predetermined time, and circulation of the ink through the first flow path, the bypass flow path and the second flow path without passing through the head when the elapsed time is longer than the predetermined time.
