PTM 2-56 B070/B071
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”,2-57) 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.
