Sheet feeder and jam detecting method |
摘要 |
A transporter is adapted to transport a sheet in a transport direction in a transport path that includes a detecting range. A measurer is disposed at an upstream end of the detecting range in the transport direction, and is operable to measure a moving distance of the sheet. A detector is disposed at a downstream end of the detecting range in the transport direction, and is operable to detect a leading end edge of the sheet. A processor is operable to detect a jam in case that the moving distance is longer than a distance of the detecting range in the transport direction while the leading end edge of the sheet is not detected by the detector.
