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] 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. 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.
