TONER SUPPLY AND RECYCLING
Meanwhile, the machine indicates that the first bottle is empty. When the user
takes out the old bottle, and puts in a new one, this is detected by the toner bottle
sensor. (!"Toner Bottle Sensors", 6-87) However, this bottle is not tested until the
second bottle is empty.
NOTE: If an empty bottle is not replaced, and the other bottle becomes empty (no
toner detected 10 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.
When the second bottle is empty, the machine switches back to the first bottle.
The first bottle is tested now, by rotating it 15 times as usual. If this bottle is also
found to be empty, the machine enters the system toner end condition. This time,
the machine cannot print until one of the toner bottle sensors detects that a new
toner bottle has been inserted (the machine does not allow the 200 extra copies).
When both bottles are empty and a new toner bottle is placed in the toner bank, the
new toner bottle is rotated 15 times to supply toner to the toner entrance tank. If the
toner near end sensor then detects toner in the toner entrance tank, the system
toner end condition is cleared. If the toner near end sensor detects there is still no
toner in the toner entrance tank, the bottle cap motor closes the toner bottle cap.
The system toner end condition continues and printing is not possible.
