PROBLEM TO BE SOLVED: To provide an inkjet recording device that can prevent erroneous detection about a sensor failure and suppress deterioration in productivity due to occurrence of down time.SOLUTION: An abnormality range is set in a range of sensor outputs of end part sensors which are provided for every line head (every color) and detect a position of an end part of a recording sheet. For instance, when only a K sensor corresponding to black color is within the abnormality range at the time of determining an abnormal value, it is determined that the K sensor is in a failure. When outputs of all sensors are within the abnormality range at the time of determining the abnormal value, it is determined that a conveying position of the recording sheet is changed (meander).SELECTED DRAWING: Figure 6 |
