Abstract
A sheet conveying device includes a conveyor, a sound collector, and circuitry. The conveyor conveys a sheet. The sound collector collects an operating sound when the sheet is conveyed. The circuitry is to extract a feature amount of the operating sound collected by the sound collector, select, among multiple sets of index data serving as index to determine whether an abnormal conveyance of the sheet is to be occurred, a set of index data corresponding to a conveyance condition of the sheet, and determine whether the abnormal conveyance of the sheet is to be occurred based on the feature amount and the set of index data selected from the multiple sets of index data.
