Patent ID: 7542172

Claim:
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: providing a portion of an image to be printed; locating a source region causing reload within the image portion; locating a destination region exhibiting reload substantially one rotation of the donor roll subsequent to the source region within the image portion; wherein locating a source region causing reload within the image portion comprises: determining a coverage level of the source region; and comparing the coverage level of the source region to a source threshold, such that if the coverage level of the source region is at least as great as the source threshold, the source region causing reload has been located; wherein locating a destination region exhibiting reload comprises: determining a coverage level of the destination region; and comparing the coverage level of the destination region to a destination threshold, such that if the coverage level of the destination region is at least as great as the destination threshold, the destination region exhibiting reload has been located; finding a minimum coverage level in a neighborhood of the source region; finding a minimum coverage level in a neighborhood of the destination region; and combining neighboring results.
