6.4.6 COLLECTING USED TONER

The toner collection coil [A], driven by the
registration motor, collects the used toner
from the drum and sends it through a tube
[B] to the used toner tank.
The toner overflow sensor [C] monitors the
level of the toner in the used toner tank [D],
and triggers a warning message on the
operation panel when the used toner tank
is almost full.
The capacity of the used toner tank is 4600
cc (about 25.3 k copies/A1 sideways [LEF]
or 15 km at 6% coverage)
• After the near overflow warning, the
machine can continue to operate and will
copy up to 20 m.
• After the 20 m copies are completed, the
overflow warning is issued and copying
can no longer be done. If the 20 m limit
is exceeded during a copy job, the copy
job is terminated and a message will be
displayed on the operation panel.
• To release the machine from the
overflow shutdown, first turn the main
power switch off/on. If the message does
not appear after 1 second, you can
continue to use the machine. However, if
the message appears again, the used
bottle must be emptied.
