①The printer uses the sensor to determine the toner level by continuously detecting the toner density level in the drum unit.

②When the toner density level is lower than a certain value, the printer issues the command of adding toner.

③If the drum unit doesn't get enough toner after the command is issued, it results in inaccurate toner level status.
