WASTE TONER COLLECTION August, 2006
6-74
Waste Toner Bottle Near-Full Sensor
When the level of the waste toner rises high enough:
• T he pressure of the top of the stack of waste toner pushes a piece of silicone
rubber, then the film pushes a feeler into the gap of the sensor [B].
• The blocked sensor signals the machine that the waste toner bottle is nearly full.
• The machine issues a near-full alert and switches off the waste toner distribution
motor.
Waste Toner Bottle Full Sensor
Monitors the level of the waste toner in the waste toner bottle. Signals an alert
when the pressure of the waste toner releases the bottle full sensor [C].
After the alert is issued, the machine can print up to 100 additional copies. After
100 copies, the machine issues SC484.
Waste Toner Lock Sensor
This sensor is located on the PTR motor bracket. It detects when the waste toner
bottle transport coil locks and stops rotating because of clogged toner in the waste
toner transport path. The machine issues SC488 if there is no change 3 seconds
after the lock occurs.
Waste Toner Transport Motor
If the waste toner transport motor does not turn for 600 ms, the motor control board
sends a motor lock signal to the CPU and the machine issues SC485.
