A method for determining if an image to be printed is subject to reload artifact, includes providing an image (which may be a low resolution version of the image) to be printed; locating within the image a first area to be printed requiring toner of sufficient quantity to cause reload of the donor roll; locating within the image a second area substantially one rotation of the donor roll subsequent to the first area; determining if the second region is a region of high area toner coverage, wherein high area toner coverage comprises toner coverage exceeding a predetermined threshold value; if the second region is a region of high area toner coverage, determining if the second region contains high frequency content; if the second region contains high frequency content, the second region is not subject to reload artifact; else the second region is subject to reload artifact.
