Fusing Temperature Control
There are two types of temperature control: On/off control (Default), and Phase control.
Either mode can be selected with SP1104 (Fusing Temperature Control).
After the machine is powered on, the CPU checks the ac frequency for 500 ms, in case
phase control is selected later for the temperature control, and then switches on the fusing
lamp.
As soon as both the center and end thermistors detect the print ready temperature (also
known as the “re-load” temperature) , the machine can operate. The “reload” temperature is
30°C below the fusing temperature (this depends on SP1105-05, 06). As soon as the
thermistors detect the fusing temperature, the CPU switches the lamps off but frequently
switches on/off again in order to maintain the fusing temperature.
Fusing Idling Temperature
If copies are not sufficiently fused soon after the power switch is turned on, fusing idling
should be enabled with SP1103-01.
When fusing idling is enabled, it is done when the temperature reaches the re-load
temperature. The re-load temperature can be adjusted with SP1105-05, 06.
In the opposite case, even if fusing idling is disabled, it is done if the temperature at
power-up ≤ 15°C
The fusing idling time is as follows.
