Fixing Sub Thermistor (Front) high temperature detection error
The Fixing Sub Thermistor (Front) in the Fixing Unit detected 297 deg C or higher for 0.2 sec or
longer.
[Related parts]
- Harnesses from the DC Controller PCB to the Fixing Thermistor
1. DC Controller PCB (UN04/J121) to Fixing Drawer (J1001DA) (Unit of replacement: FIXING
DRAWER ASSEMBLY)
2. Fixing Drawer (J1001LA) to Relay Connector (8P) (Unit of replacement: CABLE, DRAWER
RELAY)
3. Relay Connector (8P) to Fixing Thermistor (TH02) (Unit of replacement: FIXING FILM
ASSEMBLY)
- Harness between the DC Controller PCB (UN04/J115) and the Low Voltage Power Supply PCB
(UN01/J322) (Unit of replacement: POWER SUPPLY ASSEMBLY)
- Harness between the Low Voltage Power Supply PCB (UN01/J302) and the AC Interlock Switch
(SW12) (Unit of replacement: CABLE, AC INTERLOCK SWITCH)
- Fixing Unit (Unit of replacement: FIXING ASSEMBLY)
- Low Voltage Power Supply PCB (UN01) (Unit of replacement: POWER SUPPLY ASSEMBLY)
- DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER PCB ASSEMBLY)
[Remedy]
1. Check/replace the related harness/cable, connector and parts.
2. After performing the remedy work, go through the following to clear the error: COPIER>
FUNCTION> CLEAR> ERR.
[Reference] Before replacing the DC Controller PCB, back up the service mode data (approx. 2
min) and restore the backup data after the replacement so the data may be able to be protected.
- Backup: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMBUP
- Restoration: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMRES
