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.

Buckle control for reducing interactions between media drive systems

A copy media feed system includes two pair of feed rolls which are horizontally aligned to form nip areas to engage the media. Each feed roll pair comprises one drive roll and one idler roll. For one pair, the drive roll is an elastomer-covered, high friction roll and the idler roll is a hard, roll. For the second pair the drive roll is a hard, high friction roll and the idler roll is an elastomer-covered roll. This arrangement provides accurate control of the media velocity.
