Device for controlling pinless paper movement in a continuous forms printer

Image Number 5 for United States Patent #5809390.

A continuous forms printer utilizing paper without pinholes along each edge is provided with a first paper transfer device on the input side of the printing station and a second paper transfer device on the output side of the printing station. The two paper transfer devices are operated at slightly different speeds in order to place tension in the continuous forms at the printing station in order to control registration and magnification problems. For example, a vacuum transport belt is placed on the output side and operated at a slightly greater speed than the printer. The belt is provided with friction characteristics and operated at a vacuum pressure to allow slippage of the belt and paper at the desired tension. By placing positive paper control on the output side, the directional stability of the continuous forms is improved thus avoiding skew control problems.
