Abstract:
1. An image recording apparatus comprising: a carrier mechanism which comprises a carrier information generation unit which generates a number of pulse signals according to a carried distance of a recording medium transferred from an upper stream side of a carrier route toward a lower stream side; and at least one recording unit which comprises a nozzle array driving unit and at least one nozzle array formed of a plurality of nozzles in a direction orthogonal to a carrier direction of the recording medium, wherein the image recording apparatus records an image by driving the plurality of nozzles and injecting ink based on image data every time the image recording apparatus receives one line of image data transferred from a higher-order device; a recording medium detection unit which is provided on an upper stream side of the carrier mechanism in the carrier route, and which detects at least a front end and a back end of the recording medium in the carrier direction; a nozzle array control unit which controls the plurality of nozzles based on job information received from the higher-order device and based on detection of the front end and the back end of the recording medium by the recording medium detection unit, so as to inject the ink to only an area in a range between the front end and the back end of the recording medium; and a control unit which receives the image data and which notifies the higher-order device of transfer stoppage of one or more lines of the image data of a page being processed by the nozzle array control unit according to the detection of the back end of the recording medium by the recording medium detection unit.
