The following are maintenance messages that appear alternatively with the normal message on
the upper row of the LCD when the machine is in the Ready mode. These messages advise you
that you will need to replace each of the consumable items as soon as possible, since the
consumable item's end of life has been reached. The machine will continue printing when any of
these messages appear on the LCD.
