Description: Sub Thermistor (Rear) low temperature detection error
Causes: The Sub Thermistor (Rear) detected a temperature of 80 deg C or lower for 1 sec or longer from start of PI control until completion of the last rotation (the Fixing Heater is turned OFF) during printing.
Remedy: [Related parts] R1.00 - Harness between the Fixing Drawer (DR01/J5401) and the Low-voltage Power Supply PCB (UN01/J302) - Harness between the Low-voltage Power Supply PCB (UN01/J315 and J322) and the DC Controller PCB (UN04/J20 and J22) - Harness between the Fixing Drawer (DR01/J5401) and the DC Controller PCB (UN04/J134) - Fixing Assembly - Low-voltage Power Supply PCB (UN01) - DC Controller PCB (UN04) [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. - Backup: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMBUP - Restoration: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMRES

Description: Fixing Relay welding detection error
Causes: Zero cross interruption was detected although the Fixing Relay was not turned ON.
Remedy: [Remedy] Check/replace the Low-voltage Power Supply PCB. (UN01) [Caution] Since an electrical trouble due to error in fixing safety circuit relay is the cause of the error, be sure to replace the Low-voltage Power Supply PCB.

If periodic sound has occurred, check/replace the Fixing Assembly, Low-voltage Power Supply PCB, DC Controller PCB, and related harness. 2. If the Delivery Roller is rotating without noise, or if noise of the gear teeth being improperly meshed has occurred, check/replace the Fixing Drive Unit. 3. If the Delivery Roller is not rotating, check/replace the Fixing Motor, Fixing Drive Unit, Lowvoltage Power Supply PCB, DC Controller PCB, and related harness.
