to correct them, we have to look at the legend, which tells us which correction we have to apply to each pattern. If we apply these corrections we then get aligned patterns as shown at the right of the example. NOTE: This plot is always printed with the most recent alignment patterns, and thus, if the printer is perfectly aligned, all the patterns will have straight lines. Once some alignment values have changed, we recommend printing this plot to check its correctness. If this plot is not perfectly aligned, you can refine it iteratively with the procedure explained above. The diagram below shows the distribution of printheads in the carriage. NOTE: In the above diagram, 'Pen' is used to mean 'Printhead'. The following table summarizes the correction type controlled by each pattern, and the relationship between printheads and patterns.
