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.
