• Code: 227-0001-04
• Description: Power supply error
• Causes: The Reader Controller PCB did not detect 24 V when the main power was turned ON.
• Remedy: [Related parts] R1.00 - Harness between the Reader Controller PCB (UN_BO1/J104) and the DADF Driver PCB (PCB1/ J402) - Harness between the Reader Controller PCB (UN_BO1/J4) and the Relay PCB (UN5/J407) - Harness between the Relay PCB (UN5/J405) and the 24V Power Supply PCB (UN10/J834) - Reader Controller PCB (UN_BO1) - DADF Driver PCB (PCB1) - Relay PCB (UN5) - 24V Power Supply PCB (UN10) [Remedy] Check/replace the related harness/cable, connector and parts. [Reference] - When an error is detected, conduction of 24 V is stopped. At power check, check if 24 V is conducted or rated voltage is output by repeating power cycling of the machine. - Before replacing the Reader 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.
