Waste Toner Path

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][M] in the duct transport this waste toner towards the
waste toner bottle [A]. The coil [J] is driven by the development drive motor–K. The
coils [K][L][M] are driven by development drive motor-CMY. 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 [A]. There are
three openings [B][C] and one collection coil [D] in this part. The waste toner drops
into the bottle through the openings. The collection coil [D] is driven by drum drive
motor-K.
NOTE: This mechanism also removes excess lubricant (☛ 6.4.3).
