Waste Toner Bottle Full Detection - Ricoh MP C3004 Field Service Manual

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 computed 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.
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 count value of the days remaining counter displays the
days remaining from when the waste toner bottle full sensor was first switched ON.)
• There is no need to set SP3-701 (New Unit Detection) because the new bottle is detected
automatically.
