Abstract

In a multi-color electrophotographic printing machine, successive different color toner images are transferred, in superimposed registration with one another, to the copy sheet. Inorder to minimize smear and blurring of the resultant toner image, it is necessary to insure that successive toner images are transferred in registration with one another. When at least one roller supports a photoconductive belt, an indexable plate can be mounted on one end of the roller. The plate has a hole therein adapted to mesh with a pin on the transfer drum supporting the copy sheet. A servo indexes the plate to align the registration hole with the toner image on the photoconductive belt. In this way, the pin extending from the transfer drum mates with the registration hole to insure that successive toner images are transferred to the copy sheet in superimposed registration with one another.
