摘要：There are provided a paper conveying apparatus, a jam detection method and a computer-readable, non-transitory medium that suppress erroneous detection of occurrence of a jam by a sound due to a sound generated from the apparatus. 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, a sound jam detector for determining whether a jam has occurred based on the sound signal output during a paper conveying operation, a control module for performing abnormal processing when the sound jam detector determines that the jam has occurred, and an abnormal sound detector for determining whether an abnormal sound has been generated based on the sound signal output before a paper conveying operation.

主权项：1. A paper conveying apparatus comprising: a sound signal generator, provided with a sound detector near a conveyance path of paper, for generating a sound signal; an abnormal sound detector for determining whether an abnormal sound has been generated based on the sound signal output before a paper conveying operation in the paper conveying apparatus; a sound jam detector for determining whether a jam has occurred in the conveyance path based on the sound signal output during the paper conveying operation; and a control module for performing abnormal processing when the sound jam detector determines that the jam has occurred; wherein the control module determines that the jam detection based on the sound signal becomes unstable when the abnormal sound detector determined that the abnormal sound has been generated.
