To confirm the actual ink remaining, 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.
Your product’s 
ink light will also indicate
when an ink tank is low or needs to be refilled.
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
the tank could damage the product.
