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.

Abstract: A sheet conveying device includes a conveyor, a sound collector, an operation unit, and circuitry. The conveyor conveys a sheet in a sheet conveyance direction. The sound collector collects sound produced by conveying the sheet by the conveyor. The operation unit outputs information of a conveyance of the sheet. The circuitry is to cause the sound collector to collect the sound, detect a factor of an abnormal conveyance produced by conveying the sheet based on the sound collected by the sound collector, locate a position of the factor of the abnormal conveyance of the sheet in response to a detection of the factor of the abnormal conveyance of the sheet, and output, to the operation unit, the position of the factor of the abnormal conveyance of the sheet.
