Overheat Protection; Paper Exit [All Models] - Ricoh G112 Service Manual

IMAGE FUSING AND PAPER EXIT [ALL MODELS]

Overheat Protection

• If the hot roller temperature becomes greater than 240 °C, the CPU cuts off the
power to the fusing lamp. At this time, SC543 will be generated.
• If the thermistor overheat protection fails, there is a thermostat in series with the
ground of the fusing lamp. If the temperature of the thermostat becomes greater
than 210 °C, the thermostat opens, removing power from the fusing lamp. At this
time, the machine stops operation.
