Abstract: An image recording apparatus according to an embodiment of the present invention for recording an image on a recording medium by jetting ink obtains information of a jetting amount of the ink, obtains information of a flying distance of the ink in the jetting the ink, estimates an occurrence amount of ink mist, which is caused inside the image recording apparatus by the jetting the ink, based on the information of the jetting amount and the information of the flying distance, and determines whether or not to clean the inside of the image recording apparatus based on the estimated occurrence amount of ink mist.

Abstract: The present invention provides an image recording device including: a conveyance mechanism moving a record medium in a first direction; a recording unit having a recording device arranged in a second direction crossing the first direction in which the record medium moves; a side end detection unit detecting in a desired period a side end position in the second direction of the record medium which moves in the first direction; a storage unit storing detection results of the side end position; and a side end position determination unit reading the plurality of continuous detection results from the storage unit, and determining as the side end position of the record medium an average value of the detection results remaining after excluding at least one detection result indicating the side end position at a relatively outside a central portion of the record medium from the plurality of read detection results.
