Jam detection system

An apparatus for predicting a location of a sheet being advanced along a path of movement by a transport after an occurrence of a sheet jam, including:

• a jam detecting device, disposed along the path of movement of the sheet, for detecting a sheet jam along the path of movement thereof and generating a sheet jam signal;
• a sensor, operatively associated with the transport, to detect continued movement of the transport after said jam detecting device detects the sheet jam and generates a transport signal;
• and
• a processor in communication with said jam detecting device and said sensor, for receiving the sheet jam signal and the transport signal to predict the location of the sheet in the path of movement after the sheet jam occurs.

A method of predicting sheet locations of a sheet after a sheet moving along a path in a printing machine jams wherein the printing machine includes processing stations disposed about a photoconductive member to form indicia on the sheets, including:

• detecting a sheet jam along the path of movement thereof and generating a sheet jam signal;
• sensing continued movement of the photoconductive member after said detecting step and generating a photoconductor signal;
• and
• processing the sheet jam signal and the photoconductor signal to predict the sheet locations after the sheet jam occurs.
