TONER SUPPLY AND RECYCLING
When the first toner bottle is empty, the machine switches to the second toner
bottle.
The first toner bottle cap motor closes the bottle cap and the second toner bottle
cap motor pulls out the second bottle cap. The motors operate until the first bottle
inner cap sensor does not detect the actuator and the second bottle inner cap
sensor does detect the actuator.
The second toner bottle is then rotated.
When the operator takes out the old bottle, and puts in a new one, this is detected
by the toner bottle sensor. However, this bottle is not tested until the second bottle
is empty. When the second bottle is empty, the machine switches back to the first
bottle.
If an empty bottle is not replaced, and the other bottle becomes empty (toner end
condition detected 15 consecutive times, as described above), 200 more copies
can be made. Then the machine enters the system toner end condition (both
bottles are empty), and this is indicated in the operation panel display.
The system toner end condition continues and printing is not possible.
