Select Settings on the home screen.
Select Maintenance > Print Head Nozzle Check.
Follow the on-screen instructions to print the nozzle check pattern.
Check the printed pattern to see if the print head nozzles are clogged.
When Print Head Cleaning is finished, print the nozzle check pattern again. Repeat cleaning and printing the pattern until all lines are printed completely.
If print quality has not improved after repeating nozzle check and head cleaning 3 times, wait for at least 12 hours without printing, and then run the nozzle check again and repeat the head cleaning if necessary. We recommend turning off the printer by using the button. If print quality has still not improved, run Power Cleaning.
