004-0002-05 Current detection circuit error
Detection Description Current outside the specified range flowed to the Fixing Heater when the heater was turned ON.
Or, failure of fixing current detection circuit was detected.
Remedy
[Related parts]
- Harnesses from the Low Voltage Power Supply PCB to the Fixing Heater
1. Low Voltage Power Supply PCB (UN01/J302) to AC Interlock Switch (SW12) (Unit of
replacement: CABLE, AC INTERLOCK SWITCH)
2. AC Interlock Switch (SW12) to Fixing Drawer (J1001) (Unit of replacement: FIXING DRAWER

3. Fixing Drawer (J1001) to Relay Connector (3P) (Unit of replacement: CABLE, DRAWER
RELAY)
4. Relay Connector (3P) to Fixing Heater (H1 and H2/J1115) (Unit of replacement: FIXING FILM
ASSEMBLY)
- Harness between the DC Controller PCB (UN04/J121) and the Fixing Drawer (J1001DB) (Unit
of replacement: FIXING DRAWER ASSEMBLY)
- 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] Check/replace the related harness/cable, connector and parts.
[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.
