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.

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.
