Patent attributes
An inkjet printer includes: a print head; a maintaining unit; a timing unit; a notifying unit; a maintenance command determining unit; and a maintenance operation executing unit. The print head is formed with one or more ink ejection opening for printing a printing medium by ejecting ink through the ink ejection opening. The maintaining unit restores the ink ejection state of the print head by flowing ink through the ink ejection opening. The timing unit keeps track of an elapsed time after the maintaining unit has executed a maintenance operation. The notifying unit notifies a user when it is time to execute a maintenance operation if the elapsed time measured by the timing unit exceeds a prescribed time. The maintenance command determining unit determines whether or not the user has issued a command to execute a maintenance operation with the maintaining unit after the notifying unit has issued a notification. The maintenance operation executing unit executes a maintenance operation with the maintaining unit when the maintenance command determining unit determines that the user has issued a command to execute the maintenance operation.
