摘要：
A copying apparatus has a device for transporting copy material along a path, a device for detecting copy material along the path, first and second modes in which first and second timing signals are produced, respectively, and a jam detector, responsive to the absence of a detection by the detection device prior to the first or second timing signal, for producing an output.
