Waste toner on the OPC drum and on the image transfer belt is collected into the waste toner tank.
* After transferring the toner image on the OPC drum to the ITB, a cleaning blade scrapes waste
toner from the OPC drum, and the waste toner is collected into a waste toner tank.
* An Image Transfer Belt cleaner scrapes waste toner from the image transfer belt, and the waste
toner is collected into a waste toner tank.

When the waste toner tank is not installed the waste toner senor
actuator blocks light from the senor LED.
> A little waste toner
When the sensor LED light reaches the photo sensor passing
through the waste toner tank this indicates that the tank is not full.
> Waste toner tank full
When the waste toner tank is full to the level of the waste toner
sensor, the senor LED light is blocked by waste toner indicating
that the tank is full.
