Abstract
An apparatus for advancing at least two different types of substrates from a moving surface to a fusing station is disclosed. A constant speed transport positioned to receive the substrate from the moving surface advances the substrate to the fusing station. An air moving device moves air such that air pressure induces a drive force on the substrate on the transport. A sensor generates a first signal when the substrate is of a first type and generates a second signal when the substrate is of a second type. The air moving device induces a first drive force when the sensor generates the first signal and induces a second drive force when the sensor generates the second signal.
