Abstract:
1. In an electrophotographic printing system employing a magnetic roll for providing toner to a donor roll, a method for determining if an image to be printed is subject to reload artifact, comprising, for each separation of the image: providing a low resolution version of the image to be printed; locating within the low resolution version of the image a source object to be printed, wherein the source object requires toner of sufficient quantity to cause reload of the donor roll at some subsequent location on the image; locating within the low resolution version of the image a destination object a predetermined distance from the source object; determining a destination coverage of toner to be deposited over a destination region at the destination object; if the destination coverage is less than a predetermined reload value; determining a dimension of the source object; determining a dimension of the destination object; comparing the dimension of the source object to a predetermined critical source dimension; comparing the dimension of the destination object to a predetermined critical destination dimension; and locating an area subject to reload artifact if the dimension of the source object is greater than the predetermined critical source dimension and the dimension of the destination object is greater than the predetermined critical destination dimension.
