Abstract:
1. An imaging system comprising: a transport belt loop including an image receiving surface thereon, wherein the image receiving surface is moved in a downstream direction; a first marking station which applies a first image to the image receiving surface; a second marking station, downstream of the first marking station, which applies a second image to the image receiving surface; a first measuring device at a first location at a beginning of a marking section which outputs velocity measurement information related to the moving image receiving surface; a second measuring device at a second location at an end of the marking section which outputs tension measurement information related to a tension increase in the media receiving surface between the first and second locations; a device member propels the transport belt loop around an elastic coated roller thereby increasing a drag force (F) on the transport belt loop; the drag force displacing the transport belt loop and the image receiving surface thereon; wherein the second measuring device calculates the transport belt displacement (Y) based on the drag force (F) according to: x equals the distance from the first location; and, a control system in communication with the first and second marking stations, the control system being configured for determining a modified actuation time of at least one of the first and second marking stations based on the information provided by the first and second measuring devices.
