Fusing Idling Temperature
If copies are not sufficiently fused soon after the main 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.

6.13.8 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.
