Waste Toner Bottle Full Detection
The waste toner bottle full sensor is at the top of the waste toner bottle. When the waste toner in the bottle has reached approximately 90%, the sensor lifts up a feeler, and an actuator blocks the waste toner bottle full sensor. After sensor detection, the remaining number of days of use is decremented from 18 by the pixel counter.
Full detection flow
1. When waste toner reaches approximately 90% of the bottle capacity, the full sensor switches ON.
2. When the waste capacity sensor switches ON, the days remaining counter is decremented from 18.
3. Days remaining counter: At 15 days to go, a @Remote warning is given (only in models with @Remote connection).
4. Days remaining counter: At 5 days to go, a control panel message (Waste toner bottle is nearly full. Please contact service department.) is displayed. (Nearly full)
5. Days remaining counter: At 0 days to go, a control panel warning is displayed, and the machine stops.
After the full sensor switches ON, before nearly full, if the waste toner bottle full sensor has been switched OFF, it is determined that the waste toner bottle has not been replaced, and countdown of the days remaining counter continues.
The days remaining counter starts computing when a new bottle is detected, and displays the days remaining, whose upper limit is 255 and lower limit is 18, until the waste toner
