Abstract: 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.

Abstract: A computer implemented method of cleaning electrodes (such as wires) is used in a toner-based electrostatic printing device. The electrodes produce an environment containing charged toner particles to assist in electrostatic printing. The method automatically monitors at least two printing parameters that are unrelated to signals and voltages provided to the electrodes (using a processor of the electrostatic printing device). Further, this method also uses the processor automatically infers a toner contamination of the electrodes from the printing parameters. This allows the processor to automatically adjust the printing the used by the electrostatic printing device during electrostatic printing to maintain the contamination of the electrodes below a threshold.

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.

Abstract: A printing system includes a media transport pathway, a marking system disposed along the media transport pathway and a sheet media sensor capable of identifying associated sheets of media. An operating module is capable of switching the printing system between a productive condition and a non-productive condition. An advancement module is capable of advancing associated sheets of media along the media transport pathway while the printing system is in the non-productive condition. A method is also included.
