A paper feed device includes a paper tray, a set-state sensor, a paper feed unit, and a control unit. The control unit checks an output from the set-state sensor each time before the start of the intermittent paper feed. In the case where no paper feed is detected even after the prescribed number of times of the intermittent paper feed, the control unit determines that a non-feed jam has occurred. In the case where it is detected that there is no paper on the paper tray before the number of repetition of the intermittent paper feed reaches the prescribed number of times, the control unit causes the paper feed unit to terminate the retry processing and determines that, with no paper on the paper tray, it is not the non-feed jam. |
