Thermal fuse
1
Is the thermal fuse located in the fixing unit
conductive?
No
Replace the fixing unit.
Thermistor
2
Remove the fixing unit from the printer and
measure the resistance between two pins of
the 2 pin connector on the fixing PCB. Is the
measured resistance within the range of
1.0 M 1.6M (normal temperature)?
No
Replace the fixing unit.

Is the fixing heat roller located in the fixing unit
conductive?
No
Replace the fixing heat roller.
Low-voltage

PCB
4
When the power is switched on, does the
voltage at connector pin P4-1 on the main
PCB go from 5V to 0V?
Yes
Replace the low-voltage
power supply PCB assy.
Main PCB
5
Make sure if:
The EP-ED cartridge is installed in the printer
correctly.
The upper cover of the printer is closed.
A paper-loaded cassette is mounted.
No
Replace the main PCB assy.
Note: When the printer has detected a fixing unit malfunction, do not power on for about 15
minutes.
Even if the power is on, the printer will shut off the power supply to the fixing heat roller
to prevent the fixing the unit from overheating.
Replace the main PCB assy ,
the SCN harness 4P,SCN flat
cable 6P or the scanner unit.
