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.

A printing system comprising a controller to combine a flushing pattern with print job data, analyze an image of the first flushing pattern applied on a medium during production of a print job to detect a presence of one or more defective ink jet nozzles and adjust the flushing pattern from the first flushing pattern to a second flushing pattern during the production of the print job upon detecting the presence of one or more defective ink jet 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;
- and
- a controller to combine a flushing pattern with print job data, analyze an image of the first flushing pattern applied on a medium during production of a print job to detect a presence of one or more defective ink jet nozzles and adjust the flushing pattern from the first flushing pattern to a second flushing pattern during the production of the print job upon detecting the presence of one or more defective ink jet nozzles.
