Abstract

A method and system collects diagnostic data for use in diagnosing existing and potential image quality issues related to a printer. Document cover sheets and/or electronic versions of the cover sheets are routinely collected, even when there has been no reported image quality issue, to preserve a historical record of the output of the printer over an extended time period. The historical record of the images on the routinely collected cover sheets and/or electronic versions of the cover sheets include data useful in diagnosing existing and potential image quality issues related to substantive pages of the documents processed by the printer.

First claim

What is claimed is:

1. A method of collecting diagnostic data for a printer, the method comprising:
generating at least one of cover sheets and/or electronic versions of the cover sheets, the cover sheets and/or electronic versions of the cover sheets identifying documents having substantive sheets being printed by the printer;
programming the printer to (i) automatically alter at least some cover sheets and/or electronic versions of the cover sheets in response to issuance by the printer of certain pre-determined occurrences, including the issuing by the printer of an alarm or alert, the altering at least some of the cover sheets and/or electronic versions of the cover sheets including adding a message on at least some of the cover sheets and/or electronic versions of the cover sheets corresponding to the issued alarm or alert and (ii) alter certain process parameters which in turn removes feedback loop generated compensation, wherein removal of the feedback loop generated compensation results in a non-compensated cover sheet which is printed, and the non-compensated cover sheet is compared with a compensated cover sheet printed with the feedback loop compensation being active, to predict when a component of the printer will begin affecting image quality,
routinely collecting the generated cover sheets and/or electronic versions of the cover sheets; and
preserving at least some of the collected cover sheets and/or electronic versions of the cover sheets as a historical record of the output of the printer over a time period, wherein the historical record of the cover sheets and/or electronic versions of the cover sheets includes data which is used to diagnose image quality issues and potential image quality issues related to the documents processed by the printer.

2. The method of claim 1 , wherein routine collection of the electronic versions of the cover sheets include automatically scanning and storing images of the cover sheets internally within the printer, according to a predetermined electronically stored schedule.

3. The method of claim 1 , further including analyzing the cover sheets and/or electronic versions of the cover sheets for image quality problems, in order to update a database and/or take remedial action.

4. The method of claim 1 , wherein the cover sheets are selectively automatically sent to a customer service center for review by a specialist.

5. The method of claim 1 , wherein the cover sheets are manually submitted by a customer to a customer service center.

6. The method of claim 1 , wherein the electronic versions of the cover sheets are generated by manually electronically scanning images of the cover sheets by a customer, and wherein the manually electronically scanned images are electronically submitted by the customer to a customer service center.

7. The method of claim 1 , wherein the cover sheets and/or electronic versions of the cover sheets are known to contain non-confidential data.

8. The method of claim 1 , wherein the cover sheets and/or electronic versions of the cover sheets are collected routinely, wherein routinely includes collection even when no image quality issues have been identified.

9. The method of claim 1 , further comprising performing an analysis of a particular cover sheet and/or electronic version of the particular cover sheet using data retrieved from the printer generated at a time corresponding to the time the particular cover sheet was printed and/or the electronic version of the particular cover sheet was electronically saved, the analysis being accomplished by use of an image analyzer configured to analyze the particular cover sheet and/or electronic version of the particular cover sheet for image quality problems.

10. A method of collecting diagnostic data for a printer, the method comprising:
generating paper cover sheets, the paper cover sheets identifying documents having substantive sheets being printed by the printer;
programming the printer to (i) automatically alter at least some of the paper cover sheets in response to issuance by the printer of certain pre-determined occurrences, including the issuing by the printer of an alarm or alert, the altering of at least some of the paper cover sheets including adding a message on at least some of the cover sheets corresponding to the issued alarm or alert, and (ii) instructing the printer to alter certain process parameters which in turn removes feedback loop generated compensation, wherein the removal of the feedback loop generated compensation results in a non-compensated cover sheet which is printed, and the non-compensated paper cover sheet is compared with a compensated paper cover sheet printed with the feedback compensation being active, to predict when a component of the printer will begin affecting image quality,
routinely collecting the generated paper cover sheets; and
preserving at least some of the collected paper cover sheets as a historical record of the output of the printer over a time period, wherein the historical record of the paper cover sheets includes data which is used to diagnose image quality issues and potential image quality issues related to the documents processed by the printer.

11. The method of claim 10 , wherein process parameters of the printer are altered and at least one paper cover sheet is printed to yield diagnostic information while sacrificing image quality of the at least one paper cover sheet.

12. A diagnostic data collecting system for collecting diagnostic data for a printer, the system comprising:
a printer including a paper path, marking engine and software configured to generate cover sheets and substantive sheets, and configured to (i) automatically alter at least some cover sheets in response to issuance by the printer of certain pre-determined occurrences, including the issuing by the printer of an alarm or alert, the altering of the at least some of the cover sheets including adding a message on at least some of the cover sheets corresponding to the issued alarm or alert, and (ii) instruct the printer to alter certain process parameters which in turn removes feedback loop generated compensation, wherein the removal of the feedback loop generated compensation results in a non-compensated cover sheet which is printed, and the non-compensated paper cover sheet is compared with a compensated paper cover sheet printed with the feedback compensation being active, to predict when a component of the printer will begin affecting image quality; and
a cover sheet record keeping system for routinely collecting and preserving data found on the cover sheets, the data to be used for diagnosing image quality issues and potential image quality issues related to documents processed by the printer.

13. The system of claim 12 , wherein the cover sheet record keeping system includes a scanner arrangement configured to scan the cover sheets and to generate and store the electronic versions of the cover sheets according to an electronically stored schedule.

14. The system of claim 13 , wherein the scanner arrangement is incorporated into the printer.

15. The system of claim 13 , wherein the scanner arrangement is separate from the printer.

16. The system of claim 12 , further including an image analyzer configured to analyze the cover sheets and/or the electronic versions of the cover sheets for image quality problems, and then to update a database and/or take remedial action.

17. The system of claim 12 , wherein process parameters of the printer are altered to yield diagnostic information while sacrificing image quality of the cover sheets an
