Toner Density Control - Ricoh B245-62 Service Training

Toner Density Sensor Initial Setting
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.
Toner Concentration Measurement
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).
