Abstract

A method maintains an environment within an interior of a sheet feeder during dead-cycling of an image forming device to which the sheet feeder is operatively connected. The method jets pulses of air into the interior of the sheet feeder that houses two or more pieces of media therein while the image forming device is dead-cycling. By the method, the attractive forces between two pieces of adjacent media. In a stack are reduced or minimized, and feeding of multiple sheets can be reduced or eliminated.
