Abstract

The present disclosure is directed toward paper jam detection in a device employing a shingled sheet stream of paper, for example, the Xerox 4135 Laser Printer and associated output modules. Conventional paper path jam detection approaches employ electronic switches and/or sensors to detect lead and trailing edges of sheets passing through a single-sheet path. More specifically, such systems track the sheet edges to determine delays indicative of paper jams. However, in shingled sheet paper paths, where sheets are intended to partially overlay one another as they are transported, no such edge detection can be accomplished.
