• Code: E260 0001
• Description: Power supply error. Short-circuit was detected at power-on.
• Remedy: [Related parts] • Harness between the DC Controller PCB (UN04/J100 and J115) and the Low Voltage Power Supply PCB (UN01/J315 and J322) (Unit of replacement: POWER SUPPLY 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. • Backup: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMBUP • Restoration: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMRES

• Code: E260 0002
