How do I know when an ink tank needs to be refilled?

• See below.

  Check Ink Level

  To confirm the actual ink remaining, visually check the ink level in the product’s ink tank. Make sure the ink level is above the lower line on the ink tank.

  Caution:
  If the ink level is below the lower line on the ink tank, fill it to the upper line on the ink tank. Continued use of the product when the ink level is below the lower line on a tank could damage the product.
