• The ink tubes may need to be filled with ink. Flush the ink tubes as instructed below.

  Power Cleaning Using the Product Control Panel

  You can run a Power Cleaning using the control panel on your product.

  Note: After a Power Cleaning, you must turn off the product and wait at least 12 hours before running another Power Cleaning.

  1. Make sure there are no errors on the LCD screen and the output tray is extended.
  2. Visually check the ink levels and make sure each ink tank is at least one-third full.

     Caution:
     If you run a Power Cleaning when the ink levels are low, you may damage the product.

  3. Press the  home button, if necessary.
  4. Select Maintenance > Power Cleaning.
  5. Follow the instructions on the LCD screen to run the Power Cleaning. A confirmation is displayed when Power Cleaning is complete.

  If the print quality does not improve after running the Power Cleaning utility multiple times, contact Epson for support.
