6.5.5 WASTE TONER COLLECTION
The waste toner from the collection coils in the four PCUs fits into the waste-toner
collection bottle from the four openings [I][J][K][M] at the rear of the PCUs. The
toner collection coils [B][C][D][G] move the waste toner to the waste toner bottle [L].
Coils [B][C][D] are driven by the color development motor and coil [G] is driven by
the black OPC/development motor.
NOTE: The openings [I] to [M] are for these PCUs: black → [I], cyan → [J],
magenta → [K], yellow → [M].
The waste toner from the transfer-belt cleaning unit falls into the waste toner
collection bottle from a separate opening [N]. The toner collection coil [A] moves
this waste toner to the waste toner bottle.
The waste toner collection coil [H] is driven by the transfer roller contact motor.
The waste toner bottle has five seals (one at each opening). The seals prevent
scattering of waste toner.
The pin [E] at the waste toner entrance pushes the shutter spring [F] in the rear of
the PCU. Because of this, waste toner can fall into the waste toner bottle when the
left cover is closed. If the left cover is open, the shutter mechanism prevents the
waste toner from spilling out from the rear of the PCUs.
