Access the printer driver window.
Click Power Cleaning on the Maintenance tab.
Follow the on-screen instructions.
If you cannot run this feature, solve the problems that are displayed on the printer's control panel. Next, follow this procedure from step 1 to run this feature again.
If print quality has not improved after running Power Cleaning, wait for at least 12 hours without printing, and then print the nozzle check pattern again. Run Print Head Cleaning or Power Cleaning again depending on the printed pattern. If quality still does not improve, contact Epson support.
