Abstract:
1. An ink jet recording apparatus, comprising: an inkjet head in which is formed an ejection surface from which ink is ejected; a conveyor mechanism which is configured to convey a recording medium on a conveyor surface in a medium conveyance direction, so as to be opposed to the ejection surface; a sensor configured to detect, at a prescribed position, the recording medium being conveyed in the medium conveyance direction on the conveyor surface by the conveyor mechanism; a relative movement mechanism configured to move at least one of the conveyor mechanism and the ink-jet head relative to each other such that the conveyor mechanism and the ink jet head are located selectively at one of: a recording position at which an image is recorded on the recording medium with the ink ejected from the ink jet head; and a medium removal position at which a distance between the ejection surface and the conveyor mechanism is larger than that when the conveyor mechanism and the ink jet head are located at the recording position and at which a jammed recording medium which is jammed between the ejection surface and the conveyor mechanism is allowed to be removed; an output device configured to detect a prescribed operation and to output a jam-clearing completion signal indicative of completion of a jam-clearing processing for clearing the jam of the recording medium; and a controller having a jam judging portion configured to judge an occurrence of a jam of the recording medium between the ejection surface and the conveyor mechanism, the controller being configured:
