Fusing Idling Temperature
If copies are not sufficiently fused soon after the main power switch is turned on,
fusing idling should be enabled with SP1-103-1.
When fusing idling is enabled, it is done when the temperature reaches the print
ready (‘re-load’) temperature. The re-load temperature can be adjusted with SP1-
105-5, 6.
In the opposite case, even if fusing idling is disabled, it is done when the
temperature at power-up ≤ 15°C
The fusing idling time is as follows.

6.15.9 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 copier stops operating. At this time, SC542 (Fusing Temperature
Warm-up Error) will be displayed.
