ABSTRACT:
A regulating device for copying machines used in forming an image of an original on an image carrier and transferring the formed image onto a receiving material in which the relative position of image and receiving material with respect to each other before the iamge transfer can be adjusted. The copying device is provided with a margining means which in response to said adjustment is automatically adjusted for rendering image-free all the zones of the image carrier in which image and receiving material do not coincide during the image transfer, so as to prevent contamination with image-forming material and the occurrence of undesired deposition of image-forming material on the image receiving material.
