Abstract

A printing device includes an inspection system that uses variable intervals to inspect printed sheets for a print job. The variable interval sets the inspection points for the inspection process. Once a defect is detected on a printed sheet, the sheets in the paper path are cleared and separated into good and defective sets of sheets. The cleared sheets are sent to an output bin for further review. After addressing the defect, the last good sheet printed is determined and adjusted to resume printing operations.

First claim

The invention claimed is:

1. A method for print inspection recovery operations, the method comprising:
detecting a defect on a scanned sheet of a print job being printed within a printing device, wherein the scanned sheet is inspected within a variable interval;
determining a number of sheets within a paper path of the printing device based on the scanned sheet;
removing the number of sheets from the paper path;
determining a set of defective sheets within the number of sheets;
determining an amount of a consumable to correct the defect within the printing device;
generating job cost information for the set of defective sheets.

2. The method of claim 1 , further comprising sending the set of defective sheets to a first output bin.

3. The method of claim 2 , further comprising determining a set of good sheets from the number of sheets.

4. The method of claim 1 , further comprising adjusting a range for the number of sheets.

5. The method of claim 1 , further comprising adjusting a range for the set of defective sheets.

6. The method of claim 5 , further comprising updating the job cost information based on the adjusted range for the set of defective sheets.

7. The method of claim 1 , further comprising adding the amount of the consumable to the job cost information.

8. A method for print inspection recovery operations, the method comprising:
detecting a defect on a scanned sheet of a print job being printed within a printing device, wherein the scanned sheet is inspected within a variable interval;
determining a number of sheets within a paper path of the printing device based on the scanned sheet;
identifying the number of sheets from the paper path;
determining a set of defective sheets within the number of sheets;
determining a set of good sheets within the number of sheets;
sending the set of defective sheets to a first output bin of the printing device;
lowering the first output bin with the set of defective sheets; and
sending the set of good sheets to a second output bin of the printing device.

9. The method of claim 8 , further comprising determining an impression related to the scanned sheet.

10. The method of claim 8 , further comprising generating job cost information from the set of defective sheets and the set of good sheets.

11. The method of claim 8 , further comprising adjusting the set of defective sheets using a user interface connected to a digital front end of the printing device.

12. A method for recovering from an equipment malfunction defect at a printing device, the method comprising:
detecting a defect on a scanned sheet of a print job being printed within a printing device, wherein the scanned sheet is inspected within a variable interval;
determining a number of sheets within a paper path of the printing device based on the scanned sheet;
removing the number of sheets from the paper path;
determining a set of defective sheets within the number of sheets;
adjusting a first sheet of the set of defective sheets using a user interface at the printing device, wherein adjusting the first sheet includes scrolling through the number of sheets for the variable interval; and
resuming printing of the print job at the first sheet.

13. The method of claim 12 , further comprising generating job cost information based on the first sheet of the set of defective sheets.

14. The method of claim 12 , wherein adjusting the first sheet includes determining an impression for the scanned sheet.

15. The method of claim 12 , wherein adjusting the first sheet includes selecting a segment of the number of sheets.

16. The method of claim 12 , further comprising processing a subsequent print job while adjusting the first sheet.
