6.4.6 WASTE TONER COLLECTION
The waste toner from the collection augers in the four PCUs drops into the waste
toner collection duct from the four openings [F][G][H][I] at the rear of the PCUs. The
toner collection coils [J][K][L] in the duct transport this waste toner towards the
waste toner bottle [A]. The coils [J][K][L] are driven by development drive motor-
CMY.
NOTE: The openings and PCUs correspond as follows: black → [F], yellow → [G],
cyan → [H], magenta → [I].
The waste toner from the transfer belt cleaning unit drops into the waste toner
collection duct from another opening [E].
The end of the waste toner collection duct is in the waste toner bottle. There are
two openings [B][C] and one collection coil [D] in this part of the duct. If the toner is
unable to drop through the opening [C] in the middle of the bottle, it is transported
to the end of the duct and drops into the bottle through the other opening [B]. This
collection coil [D] is driven by drum drive motor-K.
