drop-out occurs . If dot drop-out is present, per-
form cleaning of the print heads .
Try an appropriate print mode . Specific combina-
tions of media and print mode may cause the

color-profile selection) . Select settings appropri-
ate for the media you are using .

exposed to direct sunlight . Doing so may result
in dot drop-out or reduced printing quality and
may even result in malfunctions .

be adversely affected . Make sure the media is
loaded and set up correctly .
