1. A method for reducing artifacts in an electrophotographic printing system, comprising:
receiving a print job including image data for a set of pages to be printed with the electrophotographic printing system;
using the electrophotographic printing system to print a block of pages from the print job to provide corresponding printed pages, wherein the electrophotographic printing system includes a development subsystem that supplies toner used to form the printed pages;
analyzing the image data for the block of pages to determine an average toner usage rate;
defining an acceptable toner usage rate range, wherein the development subsystem supplies toner with an acceptable charge when the average toner usage rate is within the acceptable toner usage rate range;
if the determined average toner usage rate for the block of pages is outside the acceptable toner usage rate range:
determining image data for a compensation image; and
determining a number of compensation images to be printed;
wherein the image data for the compensation image and the number of compensation images are determined such that the average toner usage rate will be brought back into the acceptable toner usage rate range when the determined number of compensation images are printed using the electrophotographic printing system.
