ABSTRACT:
An apparatus for predicting a location of a sheet being transported along a path of movement after the occurrence of a sheet jam. A sheet jam detecting device is disposed along the path of movement of the sheet. The sheet jam detecting device detects the sheet jam along the path of movement and generates a sheet jam signal. A sensor is operatively associated with the transport to detect the continued movement of the transport after the jam detecting device detects the sheet jam. The sensor generates a transport signal. A processor is in communication with the jam detecting device and the sensor for receiving the sheet jam signal and the transport signal. The detector predicts the location of the sheet as a function of these signals. An apparatus of this type may be used in a printing machine for detecting the location of sheets after the occurrence of a sheet jam.
