Toner Density Control – 2
The TD sensor initial setting (SP 2214: Developer
Initialize) procedure must be done after replacing
the developer. During TD sensor initial setting,
the TD sensor is set so that the TD sensor output
is the value of SP 2926 (default: 2.4 V). This
value will be used as the standard reference
voltage (Vts) of the TD sensor.
The toner concentration in the developer is
detected once every copy cycle. The sensor
output voltage (Vt) during the detection cycle is
compared with the standard reference voltage
(Vts) or the toner supply reference voltage (Vref).
