 Error code E200
When the center thermistor of the fuser unit is higher than the idle temperature, the side
thermistor detected a temperature higher than the specified temperature.
 Error codes E300 and E400
These errors do not usually occur during normal use. The possible causes are noise around
the installation site, fluctuation of the power supply voltage, and failures in the software.
An unidentified error occurred.
