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.
Temperature at power-on
Fusing Idling Mode
0: Disabled 1: Enabled SP1103-01
15°C or less 30 s 30 s
SP1103-02
Higher than 15°C Not done 30 s
Overheat Protection
If the hot roller temperature becomes greater than 250°C, the CPU cuts off the power to the fusing lamp,
and SC543 (Fusing Overheat Error) will be displayed.
Even if the thermistor overheat protection fails, there is a thermostat in series with the common ground line
of the fusing lamp. If the temperature of the thermostat reaches 210°C, the thermostat opens, removing
power from the fusing lamp. At the same time, the machine stops operating. At this time, SC542 (Fusing
Temperature Warm-up Error) will be displayed.
