You should visually check the ink levels in the product's ink tanks regularly. For optimum printing results, refill the ink tanks to the upper line at least once a year.
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.
Visually check the ink levels in the product’s ink tanks to confirm the actual ink levels. Continued use of the product when the ink is expended could damage the product.
