Printer characterization, monitoring and diagnosis using dynamic test patterns generated by sensing and analyzing customer documents

A system for automated image quality based diagnosis of a document printing system, comprising:

• a print engine configured:
• to receive image data to be printed on a document, and
• to print an image on the document based on the image data;
• a sensor configured to scan the printed image;
• and
• an image quality analysis module configured to analyze the scanned printed image to identify one or more defects on the printed image;
• wherein the print engine is configured:
• to automatically generate test pattern image data based on the one or more identified defects, and
• to print and analyze a test pattern image based on the test pattern image data.

A system for pooling image quality data related to a plurality of document printing systems to obtain automated image quality based diagnosis, comprising:

• a plurality of document printing systems, each document printing system comprises:
• a print engine configured
• to receive image data to be printed on a document, and
• to print an image on the document based on the image data;
• a sensor configured to scan the printed image;
• an image quality analysis module configured to analyze the scanned printed image to identify one or more defects on the printed image;
• wherein
• the print engine is configured
• to automatically generate test pattern image based on the one or more identified defects;
• and
• to print and analyze a test pattern image based on the test pattern image data;
• a network;
• and
• a manufacturer/service provider;
• wherein
• an image quality data is obtained from at least one document printing system by analyzing the test pattern image from the at least one document printing system;
• and
• the manufacturer/service provider is configured to receive the image quality data from the at least one document printing system via the network.
