Part 1 (top) consists of rectangles of pure colors, one for each printhead. This part represents the print
quality that you will get from each color.
●
Part 2 (bottom) consists of small dashes, one for each nozzle on each printhead. This part complements
the first, and aims more specifically to detect how many faulty nozzles each printhead has.
Please look carefully at the print. The names of the colors are shown above the rectangles and in the center
of the patterns of dashes.

First look at the upper part of the print (part 1). Each colored rectangle should be a uniform color without any
horizontal lines across it.
Then look at the bottom part of the print (part 2). For each individual colored pattern, check that most of the
dashes are present.
If you see horizontal lines in part 1 and also missing dashes in part 2 for the same color, the printhead
responsible needs cleaning. However, if the rectangles look solid, do not worry about just a few missing
dashes in part 2; these are acceptable because the printer can compensate for a few clogged nozzles.
Here is an example of a gray printhead in a good state:
