• Code: E806-0401
• Description: Duplex Cooling Fan error
  The Duplex Cooling Fan in the Right Cover rotated for more than the specified period of time after the stop of drive.
• Remedy: [Related parts] - Harnesses from the DC Controller PCB to the Duplex Cooling Fan 1. DC Controller PCB (UN04/J122) to Relay Connector (17P) (Unit of replacement: 2ST TRANS. H.V. CONTACT ASS’Y) 2. Relay Connector (17P) to Relay Connector (3P) (Unit of replacement: CABLE, DOOR, RIGHT) 3. Relay Connector (3P) to Relay Connector (3P) (Unit of replacement: CABLE, DOOR FAN, RIGHT) 4. Relay Connector (3P) to Duplex Cooling Fan (FM04) - Duplex Cooling Fan (FM04) - DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER PCB ASSEMBLY) [Points to note at work] When checking the harness/cable or connector, perform the following work. 1. Disconnect and then connect the connector to check that there is no bent pin and cable disconnection. 2. Visually check that the harness is not caught or open circuit. 3. If there is any error, replace the corresponding harness/cable. [Remedy] Check/replace the related 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

• Code: E808-0001

• Code: E880-0001
• Description: Controller Cooling Fan error
  It was detected that the Controller Cooling Fan was locked.
• Remedy: [Related parts] - Main Controller Cooling Fan (UN81/J15) (Unit of replacement: MAIN CONTROLLER PCB ASSEMBLY) - Main Controller PCB (UN81) (Unit of replacement: MAIN CONTROLLER PCB ASSEMBLY) [Points to note at work] When checking the harness/cable or connector, perform the following work. 1. Disconnect and then connect the connector to check that there is no bent pin and cable disconnection. 2. Visually check that the harness is not caught or open circuit. 3. If there is any error, replace the corresponding harness/cable. [Remedy] Check/replace the related parts.

• Code: E881-0001
• Description: Board over heat error
  Abnormal temperature of CPU on the Main Controller PCB was detected.
• Remedy: [Related parts] Main Controller PCB (UN81) (Unit of replacement: MAIN CONTROLLER PCB ASSEMBLY) [Remedy] Perform the following in the order while checking whether the error is cleared. a. If the error occurred during a service visit and then occurred again, replace the Main Controller PCB. b. If the error does not occur during a service visit but is found in the log: 1. Clean the inlet on the side where the fan is installed and remove dust. 2. Remove dust from the fan in the Controller Box. 3. If the space on the side where the fan is installed is less than 10 cm, ask the customer to secure enough space.
