ABSTRACT:
This is a simple and effective multi-feed system for use in marking apparatus where the transport of paper or other media is vital. The system is independent of the weight or type of paper used as was not the case in the prior art. The present system employs the natural strength and thickness of the paper to separate one sheet from the other. This separation is used to trigger a detector alerting the system of a multi-feed of paper.
