I refilled the ink tanks after they were expended, but my nozzle check pattern still prints with gaps. What should I do?

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

    Power Cleaning Using a Computer Utility

    You can run a Power Cleaning using a utility on your Windows or Mac computer.

    1. Make sure there are no errors on the LCD screen.
    2. Load a few sheets of plain paper in the product.
    3. Do one of the following:
      • Windows: Access the Windows Desktop and right-click the icon for your product in the right side of the Windows taskbar, or click the up arrow and right-click . Select Printer Settings and click the Maintenance tab.

    5. Follow the on-screen instructions to run a Power Cleaning.
    6. When Power Cleaning is finished, run a nozzle check.
    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.
