Zusammenfassung:	A medium transport sytem for indicating a medium jam along a medium transport path and a system thereof are disclosed. The medium transport sytem for indicating a medium jam along a medium transport path comprising one or more rollers for use in conveying the medium along the medium transport path; a microphone for detecting the sound of the medium being conveyed and producing a signal representing the sound; a processor for producing sound values from the signal and computing a moving window sum responsive to the sound values; computing a high amplitude count responsive to the sound values; and computing a post roller sum responsive to the sound values; and indicating the medium jam responsive to the moving window sum, high amplitude count, or post roller sum.
