îš„ 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.
îš„ 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.

Print Unable E2
Turn the power off and then back on again.
<User Check>
• Turn OFF the power switch. After several seconds, turn ON the power again and check
that this error is reset.
Step Cause Remedy
1
Connection failure of the side
thermistor harness of the fuser
unit
Check the connection of the side thermistor
harness of the fuser unit, and reconnect it if
necessary.
2
Connection failure of the eject
sensor PCB harness
Check the connection of the eject sensor PCB
harness, and reconnect it if necessary.
3
Eject sensor PCB failure Refer to "1.3.10 Check sensor operation
(function code: 32)" in Chapter 5 to check the
sensor operation. If the sensor operation is
faulty, replace the eject sensor PCB ASSY.
4 Fuser unit failure Replace the fuser unit.
5 Main PCB failure Replace the main PCB ASSY.
