• an image analyzer configured to analyze input image data on pages of a document arranged in a first order and to identify therefrom one or more relevant pages that provide diagnostic information regarding a state of the printing system;
• a scheduler configured to schedule printing the pages of the document in a second order different from the first order such that the one or more relevant pages are printed out of order from the first order;
• a marking engine constructed to print images on the pages of the document based on the input image data and the second order;
• a scanner for scanning the images printed on the one or more relevant pages while the remaining pages of the documents are printed;
