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

  Checking Ink Levels on Your Product

  To confirm the actual ink levels, visually check the ink levels in the product’s ink tanks. Make sure the ink levels are above the lower lines on the ink tanks.
  
  

  Note: The product has a low ink alert system. The accuracy of this system depends on the user refilling the ink tanks correctly. The product cannot directly measure the ink levels in the tanks; instead it estimates the amount of ink remaining by internally monitoring ink usage. The low ink alert system may generate inaccurate messages if the ink tanks are not refilled according to these instructions.

  As a precaution, perform regular visual inspections of the ink tanks to ensure ink levels do not fall below the lower line. Continued use of the product when the ink level is below the lower line on the tank could damage the product.
