   If print quality has not improved after repeating nozzle check and head cleaning 3 times, wait for at least 6 hours without printing, and then run the nozzle check again and repeat the head cleaning if necessary. We recommend turning off the printer using the button. If print quality has still not improved, run Power Cleaning.
