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

• See below.

  Checking the Ink Level on Your Product

  To confirm the actual ink level, 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.
  
  

  Note: The product has a low ink alert system. The accuracy of this system depends on the user refilling the ink tank correctly. The product cannot directly measure the ink level in the tank; 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 tank is not refilled according to these instructions.

  As a precaution, perform regular visual inspections of the ink tank to ensure the ink level does 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.
