Fixing oil heater ON Fixing oil heater OFF
6.5 Controlling the Fixing Oil Temperature
To ensure that the upper fixing roller is provided with a specific level of oil at all items,
the fixing oil in the upper oil pan is controlled to about 140°C by the oil heater (H9).
The temperature of the fixing oil is monitored by the fixing oil thermistor (TH5), while
that of the fixing oil heater is monitored by the fixing oil heater thermistor (TH6).
The DC controller PCB uses the readings of these two thermistors to switch the fixing oil
heater drive signal (H9_DRIVE), thereby controlling the fixing oil heater.
The fixing oil heater is turned OFF while the paper is being led.

The fixing oil is likely to be very hot. Be sure that the oil has cooled before
