Abstract
A mail tracing apparatus contains only input and output mail article detectors at the beginning and end of a mail transport path, respectively. By comparing the 'on' and 'off' times of the detectors at either end of the path, it can be determined, for example, if an initially doubled item has been separated into distinct mail articles, or if a mail article has dropped out of the path during transport. In either event, an error code is generated in the event of a non sequitur, and the tracing of subsequent mail articles may proceed without error.
