10)Toner bag full detection sensor (S13)
This sensor is a transmissive sensor to monitor the edge of the toner bag. When the toner bag
becomes full of used toner and the accumulated used toner shields the sensor path, this sensor
detects that the toner bag is full.
When either the used toner motor lock detection sensor (S14) or the toner bag full detection sensor
(S13) is turned ON, the toner bag is judged as full of used toner.
