G. Controlling the Temperature of the Photosensitive Drum

1. Control

The photosensitive drum temperature control mechanism has the following items of control:
When the error temperature is reached, the control IC turns on to shut off the power to the drum
heater.

2. Controlling the Power Using the Environment Switch SW6

As long as the environment switch (SW6) is on, the drum heater remains powered regardless of
the state (on/off) of the main switch.
When the switch is off, on the other hand, the drum heater is powered only when the main
switch is on. At the time of shipment, the switch is set to OFF.
