摘要： An ink jet printer may be provided with an ink jet head, a cam member, a cam follower, and a valve operation mechanism. The ink jet head may comprise an ink chamber, an exhaust passage communicating with the ink chamber, and an exhaust valve disposed at the exhaust passage. The cam member may comprise a cam groove. The cam member may be configured to rotate. The cam groove may comprise a first groove, a second groove, and a third groove. The second groove and the third groove may branch from one end of the first groove. The cam follower may be configured to be guided along the cam groove. The valve operation mechanism may be coupled to the cam follower. In a state where the cam follower is present in a predetermined position in the third groove, the valve operation mechanism may make contact with the exhaust valve, and the exhaust valve may be in an opened state.
