DRUM UNIT
B064 Series/B140 Series/G126 6-58 SM
6.8.10 WASTE TONER COLLECTION
Mechanism
The toner collection motor [A] drives the coils [B, C, and D].
• Coil [B] brings waste toner from the toner hopper (which originally came from
the drum cleaning unit)
• Coil [C] brings waste toner from the transfer unit.
• Coil [D] transports waste toner from both sources to the toner collection
bottle.
The toner collection bottle can hold 5000 cc of waste toner, equivalent to about
1,000K copies.
Motor [A] switches on and off at the same time as the drum motor.
Error Detection
The toner collection motor sensor [E] monitors the gear driven by motor [A]. If the
sensor output does not change for 3 seconds while motor [A] is on, then SC590
(Toner Collection Motor Error) is logged.
If the toner collection coil sensor [F] (not shown) does not change within 3 seconds
after the drum motor turns on, the transport coil is clogged and cannot rotate, then
SC495 (Toner Recycling Unit Error) is logged.
When the toner overflow switch (not shown) detects that the toner collection bottle
[G] is full, operation halts after an additional 100 copies and the machine prompts
the user to replace the toner collection bottle.
The toner collection bottle set switch [H] detects when a new toner collection bottle
is installed. If installing a new bottle does not reset the machine, SC496 (Toner
Collection Bottle Error) is logged.
