Warning Messages
The following warning messages indicate conditions that require operator intervention, such as
when the output tray fills up with paper, or when a particular consumable has reached the end
of its life. The "end life" message remains until you replace the consumable. Always replace
the consumable as soon as possible to maintain the best print quality.
Caution If you ignore the "Toner low" message, eventually the printer will shut down with
the "Toner empty" message to prevent mechanical damage.
Caution If you ignore the "Developer end-life" message, eventually the printer will shut
down with the "Developer end-life/Change developer at once" message to prevent mechanical
damage.
