Abstract
A method is disclosed. The method includes analyzing an image of a first flushing pattern applied on a medium during production of a print job to detect presence of one or more defective ink jet nozzles and adjusting to a second flushing pattern during the production of the print job upon detecting the presence of one or more defective print head nozzles.
Claims20
A method comprising:
- analyzing an image of a first flushing pattern applied on a medium during production of a print job to detect presence of one or more defective ink jet nozzles;
- and
- adjusting to a second flushing pattern during the production of the print job upon detecting the presence of one or more defective print head nozzles.
A printing system comprising:
- one or more print engines each having a plurality of ink jet nozzles to print a flushing pattern on a medium;
- a reader to capture an image of the flushing pattern;
- and
- a controller to analyze the image of the first flushing pattern applied on the medium during production of a print job to detect presence of one or more defective ink jet nozzles and to adjust to a second flushing pattern during the production of the print job upon detecting the presence of one or more defective ink jet nozzles.
