Methods and devices determine the media properties of a sheet of media exiting a printing device. The methods and devices apply the media properties to a predetermined velocity equation to calculate a corresponding sheet exit velocity for the sheet of media that will optimize stack quality in a particular output tray. Then, the methods and devices change process controls sheet movement elements within a media path of the printing device to cause the sheet of media to exit the printing device at the sheet exit velocity.

Controlling exit velocity of printed sheets being stacked to optimize stack quality

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.
