摘要： A novel sheet conveying device includes a conveyor, a sound collector, and circuitry. The conveyor conveys a sheet in a sheet conveyance direction. The sound collector collects sound produced by a conveyance of the sheet. The circuitry is to cause the sound collector to collect the sound in an abnormal determination operation, determine whether an abnormal conveyance occurs based on the sound collected by the sound collector in the abnormal determination operation, cause the conveyor to convey the sheet at a first speed in the sheet conveyance direction in a normal conveyance operation, and cause the conveyor to convey the sheet at a second speed slower than the first speed in the sheet conveyance direction in the abnormal determination operation.

摘要： A sheet processing apparatus includes a sheet entrance portion, a post-processing device, and circuitry. The sheet entrance portion receives a sheet medium conveyed from an upstream apparatus. The post-processing device separates a two-ply sheet, inserts the sheet medium into the two-ply sheet, and performs a heating operation on the two-ply sheet in which the sheet medium is inserted. The circuitry causes the post-processing device to interrupt a post-processing operation, as one of a series of post-processing operations up to the heating operation, in response to an occurrence of an abnormal condition of the upstream apparatus, and resume the post-processing operation interrupted due to the abnormal condition of the upstream apparatus, in response to a recovery from the abnormal condition of the upstream apparatus.

摘要： An image forming apparatus includes a stacking unit, an access detecting unit, a malfunction detecting unit, a counting unit, and a process deciding unit. The stacking unit receives, as stacked, a recording material. The access detecting unit detects an access to the stacking unit by an operator. The malfunction detecting unit detects that a conveyance malfunction of the recording material has occurred on a conveying path guiding the recording material supplied from the stacking unit. The counting unit counts, after the access detecting unit detects an access to the stacking unit by the operator in a state that the malfunction detecting unit does not detect that the conveyance malfunction has occurred, the number of the conveyance malfunction detected by the malfunction detecting unit. The process deciding unit decides a process to address the conveyance malfunction based on the number of the conveyance malfunction counted by the counting unit.
