The print is divided into two parts, both of which test printhead performance.

●

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:
