6.22.11 FUSING TEMPERATURE CONTROL (B044/B045/B046)

Overview

[A]: Thermistor
[B]: Thermoswitch
[C]: Thermofuse
The CPU checks the thermistor
[A] output once per second, and calculates the power-on ratio for the next second
based on (a) current temperature, (b) the temperature 1 second earlier, and (c) the

target temperature.

The target fusing temperature drops somewhat over time, as the machine's overall
state changes with continued use. For normal copying, the target starts at 180°C,
then drops to 170°C after one minute.

Fusing Temperature Control for Thick Paper

Target temperature goes up 10°C if the user selects thick-paper mode.
