Abstract: An apparatus includes a xerographic cleaning blade, an actuator member operatively connected to the cleaning blade and movable over a first stroke from a first actuator position to a second actuator position, and a damper operatively connected to the actuator member. As the actuator member moves over the first stroke the cleaning blade moves from a first blade position to a second blade position. The damper allows substantially uninhibited actuation of the actuator member over a first portion of the first stroke. The damper damps actuation of the actuator member over a second portion of the first stroke.

Abstract: 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 air knife employs a thick boundary layer of air at a low pressure to suspend and separate the sheets by aerodynamic drag, resulting in about a 50% reduction in the required power for operation of conventional top vacuum corrugation feeders.
