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 by sound due to the sound which a paper which has a wrinkle generates. The paper conveying apparatus includes a separator, a sound signal generator, provided with a sound detector provided at a downstream side of the separator, for generating a sound signal in accordance with the sound generated by a paper during conveyance, a sound jam detector for determining whether a jam has occurred based on the sound signal, and a wrinkle detector, provided at a downstream side of the separator, for detecting optically a wrinkle of a paper, wherein the sound jam detector changes the method of detection of the jam when the wrinkle detector detects a wrinkle of a paper.
