A multifunction blower in which a common housing is employed to both increase and decrease the pressure of incoming air in separate chambers thereof. The increase and decrease in air pressure is adjustable by changing the impellers of the pressure and vacuum assemblies used therein.

A top vacuum corrugation feeder employs a vacuum feedhead working in conjunction with an air knife to feed sheets from the top of a stack. The feedhead is valveless and has a vacuum applied thereto during the entire feed cycle in order to increase reliability and decrease minimum feed speed. The air knife includes trapezoidal shaped fluffer jets in front of the stack and side fluffer jets and added on the sides of the stack in order to assist the feedhead in separating severely downcurled sheets for feeding. A rotational damper member is positioned above and has a portion thereof resting on the stack for controlling sheet flutter and leakage of air from the stack sides. A belt coast control member controls the precise stopping position of vacuum belts that surround the vacuum feedhead in order to minimize multifeeding of sheets from the stack.

A combination electro-optic sensor and switch including a printed wiring board supporting an electro-optic sensor enclosed in a sealed housing, a sleeve mounted on a shaft for rotation within the housing in the light path the electro-optic sensor with a portion of the shaft extending through the sealed housing and connected to a wire actuator, the engagement of the wire actuator by a copy sheet providing an approximately 20 millisecond response time of the sensor.
