    Abstract: A stack height assembly consisting of two transmissive sensors (340,350) and two flags, the stack height of a feeder module (200) can be set to three different levels depending on the weight of the media. This "optimization" of the stack height to address the media's failure mode results in increased latitude. When feeding lightweight media, the stack height is set larger in order to increase the gap to the feedhead. This allows more room for separation of the media using fluffer jets (360). This increased gap also reduces the chances that the un-acquired media will be fluffed into contact with the acquisition surface and subsequently be shingle fed into the take away roll (400) due to the friction between sheets. When feeding heavyweight media the stack height will be set smaller. This reduces the gap to the feedhead (300) and reduces the time required to acquire.

    Abstract: A feed apparatus in which varying air pressures in combination with tray angling and height adjustment reduces the variability in key feeder performance characteristics such as "sheet acquisition times" and "sheet separation". The setting of positive and negative air pressures in the paper feeder based on specific paper/media characteristics sheet basis weight, size, coating configuration, curl direction and magnitude.is performed. As a result of this reduced variability, the feeder's performance (as measured by misfeeds, late feeds and multifeeds) is inherently better than designs not incorporating this concept. This concept also reduces the need for operator interventions (flipping, rotating and/or replacing paper) for feeder performance problems that are the direct result of differing paper properties (sizes ,weights & coatings) and normal variations in sheet curl from ream to ream, or from paper to paper.

    Abstract: A feed apparatus which combines a slider crank feed head (300) drive system (310) and cam (348) actuated stack height sensing system (352) to form a new combined shuttle feeder. The new feed head drive includes the replacement of a solenoid drive with a more reliable stepper driven twin slider crank drive. Included in the slider crank drive for the feed head (300) is an integral cam (348) as part of the crank arm mounted to the motor shaft (310). This cam (348) drives a stack height sensor to drop and lift the stack height sensing arm (352) to sense stack (53) height after the sheet trail edge has passed the point of arm contact with the stack (53). The cam (348) also provides a "service mode" position for the stack height arm (352) which lifts it out of the way of the paper supply when it is opening. The cam (348) dwells in a neutral home position during the rest of the drive out and return motion of the feed head (300).
