Cleaning the Print Head Using the Product Control Panel

You can clean the print head nozzles using the control panel on your product.

Make sure there are no errors on the LCD screen.
Load a few sheets of plain paper in the paper cassette.
Press the home button, if necessary.
Select Maintenance. You see this screen:
Select Print Head Cleaning. You see a screen like this:
Select Start to clean the print head. The power light flashes throughout the cleaning cycle and stays on when the cleaning cycle is finished. When the cleaning cycle is finished, you see a message on the screen.
Caution:

Never turn off the product or open the printer cover during a cleaning cycle or you may not be able to print.
Select Check.
Select Print to print a nozzle check pattern and confirm that the print head is clean.

If you don’t see any improvement after cleaning the print head up to 3 times, turn off the product and wait at least 6 hours without printing. Then try cleaning the print head again. If quality still does not improve, run a Power Cleaning. If there is still no improvement, contact Epson support.
