Abstract
In a document copier/printer wherein copy sheet is of a length which exceeds the distance between a transfer station and a fusing station, a velocity differential is established between the two stations so that the copy sheet forms a buckle therebetween which varies from an initial position, and in a predetermined direction, during operation. A sensor detects when the buckle reaches a predetermined configuration and sends a signal to one of the two stations to change the media speed at that location for a length of time sufficient to restore the buckle to the original configuration. The cycle may be repeated several times during a process run.
