prints in color.
In the check pattern, if you find that any segments are missing
from the test lines, you may need to repeat the head cleaning

If print quality hasn’t improved after repeating this procedure
four or five times, try other recommendations listed in this
chapter. If the print quality still has not improved, contact your
dealer.
