2.7.2 TONER BANK
Toner Bottle Switching Mechanism
When the upper toner bottle [A] is supplying toner, the upper bottle cap motor [B] pulls
out the toner bottle cap. The upper bottle cap sensor [C] detects the actuator [D] of the
toner bottle opening rod, then the motor shuts off to close the cap again.
Toner is supplied from the toner bottle to the toner entrance tank where a toner near
end sensor (see the next page) checks for the presence of toner in the toner entrance
tank.
When the toner near-end sensor (not shown) can no longer detect any toner, it signals
the machine that it is time to switch bottles. The upper bottle cap motor switches on
and closes the cap of the top bottle, while the lower bottle cap motor [E] switches on
and opens the cap of the lower bottle so it can start supplying toner.
