Print-quality issues 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 light gray printhead in a good state: ENWW The Image Diagnostics Print 173

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.
