Claim:
1. A method of monitoring transport of a sheet media though a media processing apparatus comprising steps of: conveying at least one sheet media with a transport apparatus including one or more rollers from a queue mechanism along a medium transport path; detecting a vibration propagating in the media processing apparatus using at east one vibration detection unit and generating detected vibration signals; detecting, with at least one sound acquisition unit, the sound of the medium being transported and producing sound signals; weighting the sound signals by combining information from the at least one vibration detection unit and the at least one sound acquisition unit; analyzing, in a processing system, the detected vibration signals and weighted sound signals, wherein the analyzing includes determining whether the detected vibration signals and weighted sound signals are associated with normal or abnormal handling of sheet media in the media processing apparatus; signaling an error condition to a control system in response to determining that the detected vibration signals and weighted sound signals are associated with abnormal handling of the sheets.
