Abstract
An electrophotographic printing machine in which successive electrostatic latent images are recorded on a moving photoconductive belt. Each latent image is adapted to be recorded in a designated region on the photoconductive belt. The designated regions are separated from one another by an inter-image zone. A test patch is recorded in the inter-image zone. The number of designated regions on the photoconductive belt is adjusted so that the size of the inter-image zone is increased enabling a portion of the latent image to be recorded in the inter-image zone without overlapping any portion of the test patch.
