Toner collected by the transfer belt unit is transported to the toner collection bottle
[A] through the toner collection tube. Three helical coils transport the toner.
One coil [B] feeds the toner in from the transfer belt unit. The next coil [C], driven
by the drum motor via drive belts, feeds the toner through the toner collection tube,
and the final coil [D], driven by the toner collection motor [E], feeds the toner to the
toner collection bottle. This toner is to be disposed of as waste.
The toner collection motor sensor [F] monitors the rotation of the toner collection
coil using the actuator disk [G] to prevent the coil from being damaged by toner
clogged in the collection tube.
When the toner collection bottle becomes full, the toner pressure in the bottle
increases and presses the gear [H] against the toner overflow switch [I]. After the
toner overflow switch is activated, the copy job is allowed to end, or up to 100
continuous copies can be made, then copying is disabled and the service call "full
toner collection bottle" is displayed on the LCD.
This condition can be cleared by de-actuating the toner overflow switch while de-
actuating then actuating the toner collection bottle switch [J].
