- Harness between the Reader Controller PCB (UN_BO1/J104) and the DADF Driver PCB (PCB1/
J402)
- Harness between the Reader Controller PCB (UN_BO1/J101) and the AC Driver PCB (UN30/
J118)
- Harness between the AC Driver PCB (UN30/J112) and the 12V/24V Power Supply PCB (UN5/
CN52)
- Reader Controller PCB (UN_BO1)
- DADF Driver PCB (PCB1)
- AC Driver PCB (UN30)
- 12V/24V Power Supply PCB (UN5)
[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.
