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.
