Abstract
A system and method for identifying a foreign object in a stack of media items is disclosed. An upper clamping plate and an opposing lower clamping plate are positioned to hold a received stack of media items. Each clamping plate has an array of capacitive electrodes positioned on an inner surface thereof. Each of the capacitive electrodes in the one array positioned directly across from a corresponding one in the first array to form a capacitive electrode pair. A controller measures the capacitance of each capacitive electrode pair when the received stack of media items is positioned between the clamping plates, determine if a foreign object is present within the received stack of media items based on the capacitance measurements from each capacitive electrode pair, and generate a signal indicating that a foreign object has been detected when a foreign object is determined to be present.
