Fixing Unit pressurization error
The pressurization of the Fixing Pressure Release Sensor (S53) was not detected for 1.5 seconds
during the Fixing Motor(M2) pressurization drive.
[Related parts]
- Harness connecting from the DC Controller PCB (UN2/J307) to the Fixing Pressure Release
Sensor (S53/J710)
- Fixing Pressure Release Sensor (S53)
- DC Controller PCB (UN2)
[Remedy]
1.Check/replace the harness and connector between the DC Controller PCB and the Fixing Main
Thermistor.
2.Replace the DC Controller PCB.
[Reference]
Before replacing the DC Controller PCB, back up the service mode data and restore the backup
data after the replacement so the data may be able to be protected.
