PROBLEM TO BE SOLVED: To surely detect control abnormalities in driving of a recording head without decreasing throughput. SOLUTION: A first detection position is set at a position separated by a first predetermined distance from a previously detected home position. A second detection position is set at a position separated by a second predetermined distance in the opposite direction to the first detection position. Whether or not a carriage driving part is a control abnormal state is identified on the basis of detection results of a home position detection sensor when the present position of the recording head is set to be the first detection position and when the present position of the recording head is set to be the second detection position.
