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 no 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.
