Abstract
New consumables installed in printing devices sometimes must print several pages to “condition” the consumable before use. This “conditioning” is required to allow various components to reach optimal condition for printing. The present invention seeks to ameliorate the situation of changes in a consumable affecting the print quality by modifying the printing behavior based on measurements made on the consumable or on the history of the consumable which is installed. If necessary, the new consumable is pre-conditioned before additional page are printed. Pre-conditioning is accomplished by printing either several test pages or by developing several images and subsequently cleaning these images into the waste toner hopper.
