You can
check the print head nozzles using the control panel on your
product to check for clogged nozzles.
If you don’t
see any improvement after cleaning the print head up to 4 times,
wait at least 6 hours without printing. Then try cleaning the print
head again. If quality still does not improve, one of the ink packs
may be old or damaged and needs to be replaced. You can also try
running a Power Cleaning.
