ABSTRACT:
A device is disposed in the path of paper leaving a printing unit or processor such as an office copier, facsimile or non-impact printer and has an arcuate concave guide and a feed roll which causes the paper to pass between the guide and the feed roll to decurl the paper. The space between the guide and the roller is greater than the thickness of the paper and the paper is bent in the direction opposite to its curl as it passes through the arched space, while the beam strength of the paper and the change in direction of the paper maintain adequate drive friction on the paper. The feed roll is mounted for movement laterally of the direction of paper travel to cause it to be laterally displaced or offset.
