I see a communication error when I try to print with a USB connection. What should I do?

• Try the following:
  • Make sure the USB cable is a shielded "AB" cable not more than 10 feet long.
    
    Note: Do not use devices that extend the length of the cable because they can cause signal degradation.
  • If you're using a switch box or USB hub, connect the product directly to your computer.
    
    Note: Do not connect through a USB keyboard. The keyboard acts like a hub and can interfere with signal transmission.
  • Use a different port on your computer.
  • Make sure there is no error on the product.
