ABSTRACT:
A method measures the location of a sheet and then moves the sheet to a registered position. By measuring the actual location of the sheet and then moving the sheet to the registered position, the invention saves a substantial amount of time. An elongated array of LED sensors130stretches over several inches and is aligned with a collimated light source110.Each sensor in the array is spaced from its adjacent sensor by a known amount. This amount can be as small as a few tens of thousandths of an inch. The edge of a sheet covers the sensors. The sheet edge is measured and the registration device moves the edge of the sheet to the registered position for receiving the developed image.
