Abstract
A device is disposed in the path of paper sheets leaving a printing unit or processor such as an office copier or non-impact printer and has an arcuate concave guide and a roll spaced from the guide to form a sheet path which is curved or arched oppositely to the direction in which the sheet is curled in the processor. 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 sheet. A selector isolates the de-curler when it is not needed.
