Abstract
A sheet conveying device includes a conveyor, a sound collector, and circuitry. The conveyor conveys a sheet. The conveyor conveys a sheet in a sheet conveyance direction. The sound collector collects an operating sound generated by a conveyance of the sheet. The circuitry is to extract a feature amount of the operating sound collected by the sound collector, and determine, at different positions in the sheet conveyance direction based on the feature amount, whether an abnormal conveyance of the sheet occurs until the sheet is conveyed to a given position in the sheet conveyance direction.
