Interpret the Printhead status plot
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 detects how many faulty nozzles are on
each printhead.
First look at the top part of the print. Each colored rectangle should be a uniform
color without any horizontal lines across it.
Then look at the bottom part of the print. For each individual colored pattern, make
sure that most of the dashes are present.
If you see horizontal lines in the top part and also see missing dashes in the bottom
part for the same color, the printhead for that color needs to be cleaned. However,
if the rectangles look solid, do not worry about a few missing dashes in the bottom
part, because the printer can compensate for a few clogged nozzles.
