HECKING CONSUMABLE
At any time, you can check how much of each consumable/
maintenance item is left by using the appropriate menus. For

Configuration>Supplies Life>Cyan Toner
The percentage of Cyan Toner remaining is displayed on the display
panel and the printer then returns to the ready to print status.

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.
The paper feed rollers and the multi-purpose (MP) tray feed rollers
do not have any replacement warning messages. Recommended
replacement: after approximately 120,000 Letter sheets.
