The following are Maintenance Messages that appear alternatively with the
“READY” message on the upper row of the LCD when the printer is in the
READY state. These messages advise you that you will need to replace
each of the consumables as soon as possible, since the consumable end of
life has been reached. The printer will continue printing when any of these
messages are displayed:
