EPLACEMENT INDICATIONS
The display panel provides messages to the effect that consumables/maintenance items
are running low or nearing end of life followed some time later by a message that
replacement is required. You should replace the item as soon as possible after this message
is displayed to avoid the possibility of print quality being compromised.
