The waste toner bottle full sensor (S34) 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 (S34). 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 operation panel message (Replacement of Waste Toner Bottle will soon be necessary. Prepare Waste Toner Bottle replacement.) is displayed. (Nearly full)
  5. Days remaining counter: At 0 days to go, a operation panel warning is displayed, and the machine stops.

  • After the full sensor switches ON, before nearly full, if the waste toner bottle full sensor (S34) 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 the lower limit is 18 until the waste toner bottle full sensor (S34) is first switched ON.
  • After the full sensor was first switched ON, the days remaining which is computed from when the sensor switched ON is displayed (upper limit is 18).
  • When the bottle is replaced before the machine detects a full waste toner bottle and stops printing, it is necessary to reset PM counters manually (SP3-701-142).
  • When the bottle is replaced after the machine stopped due to detecting a full waste toner bottle, it is not necessary to reset PM counters. If the counters are reset, the replace counter will count up twice.
