Apparatus for transporting sheets of paper
摘要:
A present sheet transporting apparatus for use in a copier measures the time for the sheets to travel a specific distance and corrects a period of time counted by a paper jam detecting timer. Therefore, if slight wear of rollers delays an arrival time of sheet, the apparatus does not detect a jam because such a delay causes no particular trouble to copying operation.
