 Fixing Temperature Control

Overview

Temperature control of the Fixing Assembly is performed by the Fixing Heater control circuit and Fixing Heater safety circuit
according to the command of the DC Controller.

Description

The DC Controller PCB monitors the fixing temperature detection signal and outputs a fixing control signal according to the
detected temperature. The fixing control circuit controls the Fixing Heater on the basis of this signal, and controls the temperature
of the Fixing Heater to the target value.
