This machine has 3 ways to prevent overheating: soft-overheat detection, hard-overheat detection, thermostat
The component call-outs correspond to the diagram below.
Heating Roller | Pressure Roller | |
|---|---|---|
Soft-overheat Detection | For all machine types SC543-00 Name: Thermopile [H] Detection Temp.: More than 240℃ SC563-00 Name: Thermistor [I] Detection Temp.: More than 250℃ | For all machine types SC553-00 Name: Thermopile [J] Detection Temp.: More than 220℃ |
Hard-overheat Detection | For all machine types SC544-00 Name: Thermopile [H] Detection Temp.: More than 250℃ SC564-00 Name: Thermistor [I] Detection Temp.: More than 260℃ | For all machine types SC554-00 Name: Thermopile [J] Detection Temp.: More than 250℃ |
Thermostat | When the thermostat detects an abnormality, SC689-00 or SC582-01 occurs. | When the thermostat detects an abnormality, SC555-00 or SC552-02, 03 occurs. |
| If a thermostat has been activated, replace the entire fusing unit. It’s possible that the IH coil [F] / the fusing belt [D] / the heating roller [E] / the fusing roller [C] / the pressure roller [L] are damaged. | ||
