[2] Waste toner tube
[3] Waste toner screw
[4] Toner developing assembly exhaust outlet
[5] ITB cleaning unit exhaust outlet
[6] Waste toner bottle
[7] Waste toner
[8] Waste toner screw drive gear
M3: Developing motor
SW5: Waste toner lock detection switch
PS63: Full waste toner sensor (magnetic sensor)
DC-CON: DC controller
The following are the detailed explanation for each detection.
Detection by magnetic sensor
The magnetic sensor (PS63) installed at the back of the waste toner bottle detects the waste toner level. This detection is performed when the waste toner level is 0
to 80%. The detection results are sent to the DC controller.
When the waste toner level reaches 80%, the DC controller notices the full waste toner alarm to the main controller.
Memo:
The magnetic sensor changes the output due to the carrier level in the waste toner to detect the magnetic substance.
The DC controller judges from the change of the sensor output that 80% of waste toner is collected into the waste toner bottle.
This machine does not have the function of detecting presence/absence of the waste toner bottle.
