 Error code 5800
Any of error codes 6A00 to 6F00, 7600, 7800, DD00, DE00, or E200 (fuser unit error)
occurred when the power switch was turned ON or sleep mode was released.
Error code 5900
Rechecking the error after the power switch was turned OFF and then ON again because an
error was detected by the center thermistor of the fuser unit.
(This message is displayed for approximately 15 minutes when the machine is restarted after
error code 5800 has occurred.)
 Error codes 5A00 to 6200
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.
Fuser Error
Self-Diagnostic
Step Cause Remedy
1
Connection failure of the fuser
unit harnesses
Check the connection of fuser unit harnesses,
and reconnect them 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 Fuser unit failure Replace the fuser unit.
4
Eject sensor PCB failure Refer to "1.3.8 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.
5
Low-voltage power supply PCB
failure
Replace the low-voltage power supply PCB
ASSY.
6 Main PCB failure Replace the main PCB ASSY.
CAUTION:
• Turn OFF the power switch. After the fuser unit has cooled sufficiently, turn ON the
power switch again and leave the machine for ten minutes. This problem may then be
cleared.
