The waste toner bottle set sensor [A] judges whether the waste toner bottle [B] is set properly or not.
The waste toner near full sensor [C] detects when the waste toner bottle is getting full. As the waste toner piles up in the waste toner bottle, the feeler [E] is pushed by the waste toner, and then the feeler interrupts the waste toner near full sensor [C]. Then the machine assumes the waste toner bottle is in a near-full state. Waste toner bottle full detection occurs at 30K for MP C6503/C8003, or 12K for Pro C5200S/C5210S after near-full detection. The waste toner flows into the waste toner bottle from the central part, and then it falls down to the front and rear in order not to pile up all in one place.
When the waste toner bottle [B] is placed in the machine, the magnet catch [D] attracts the plate that is attached to the waste toner bottle [B] in order to set the waste toner bottle correctly. At this time, the waste toner bottle pushes the waste toner bottle set sensor [A] that detects whether there is a waste toner bottle in the machine.
