Abstract: An apparatus for registering a sheet with a developed image on a moving surface. The apparatus includes a transfer station, detector, memory, and a registration transport. The detector is located at the transfer station and generates a registration signal in response to a sheet edge and a registration portion of the developed image. The memory stores sheet position factors and responds to the detector to update the factors. The registration transport communicates with the detector and the memory to move the sheet to the transfer station in registration with the developed image.
