Abstract
There are provided a paper conveying apparatus, a jam detection method and a computer-readable, non-transitory medium which can suppress erroneous detection of the occurrence of a jam. The paper conveying apparatus includes a sound signal generator, provided with a sound detector near a conveyance path of paper, for generating a sound signal corresponding to a sound generated by a paper during conveyance of the paper, a sound jam detector for determining whether a jam has occurred based on a predetermined sound signal, and a control module for performing an abnormal processing when the sound jam detector determines that the jam has occurred and the predetermined sound signal is not generated at a predetermined timing, and determining that the jam has not occurred and not performing the abnormal processing when the sound jam detector determines that the jam has occurred and the predetermined sound signal is generated at the predetermined timing.
