5. Detecting the Waste Toner Feeding Screw
State (lock)
If the waste toner inside the waste toner feed-
ing pipe cakes for some reason, it could prevent
the waste toner feeding screw from turning.
To prevent such a problem, the NP6085 uses
a feeding screw lock detection mechanism.
The gear
A
(Figure 3-330) used to drive the
waste toner feeding screw is subjected to force in
the direction of the shaft when the feeding screw
gets locked, and the condition causes the gear to
move on the shaft.
The waste toner feeding screw lock detecting
switch (SW20) is used to detect such movement
of the gear
A
.
When SW20 is pushed by the gear
A
, the
waste toner feeding screw lock detection signal
(
=0) is sent to the DC controller PCB, caus-
ing the drum motor (M1) to stop and ‘E013’ to be
indicated on the control panel.
