Abstract
There are provided a paper conveying apparatus, a jam detection method and a computer-readable, non-transitory medium that can suppress erroneous detection of a jam. The paper conveying apparatus includes a sound signal generator for generating a sound signal, a sound jam detector for determining whether a jam has occurred based on the sound signal, a special sound detector for determining whether a special sound has been generated based on a component of the sound signal, and a control module for performing abnormal processing when the sound jam detector determines that a jam has occurred and the special sound detector determines that a special sound has not been generated, and determining that no jam has occurred and not performing the abnormal processing when the sound jam detector determines that a jam has occurred and the special sound detector determines that a special sound has been generated.
