ABSTRACT:
A system for determining the proper operation of a feeding apparatus includes a detector for detecting the feeding of two or more overlapped documents. The detector is connected to a processor for processing detected information and providing an output signal indicating that the detector has detected the presence of two or more overlapped documents. An adjustment arrangement is connected to the detector for adjusting the detector to detect the presence of overlapped documents for various different types of documents to be utilized with the feeding apparatus. A display is connected to the detector which displays a first condition when no documents are detected by the detector, a second condition when a single document is detected by the detector and a third condition when overlapped documents are detected by the detector. The system may include two or more spaced apart detectors each with their own adjustment arrangement and associated display.
