Print head needs cleaning
• If there are no gaps, click Finish.
• If there are gaps or the pattern is faint, click Clean to clean the print head again.
If you don't see any improvement after cleaning the print head up to 4 times, leave the product turned on
and wait at least 6 hours. Then try cleaning the print head again. If quality still does not improve, one of
the ink cartridges may be old or damaged and needs to be replaced.
