What it means
The Kyocera operation guide shows the message Waste Toner Box is full or placed improperly when the box that collects surplus toner reaches capacity or is not seated correctly. Kyocera treats it as a supply you replace yourself: open the waste toner cover, take the box out, seal it in the plastic waste bag and fit the new one. The message does not mean the printer is broken; if it stays with a new box seated correctly, that is a different matter.
