SC1xx: Scanning
D0CA/D0C9/D0C8/D0CB 6-14 SM
No. Type Details (Symptom, Possible Cause, Troubleshooting Procedures)
SC161-20 D BiCU Error (DRAM initialization failure)
The DRAM initialization flow is not completed successfully.
This SC is detected when: the main power is turned ON and the machine
returns from the energy saver mode.
• Defective BiCU (PCB1)
• Defective DRAM device
Check if the SC occurs by turning the power OFF then ON. If the SC occurs
again, do the following steps. Check if the SC reoccurs by cycling the power
after each step.
1. 1. Reconnect all the connectors on the BiCU board if disconnected, or
loose.
2. 2. Replace the BiCU (PCB1).
No. Type Details (Symptom, Possible Cause, Troubleshooting Procedures)
SC180-01 B BiCU Error (Double-feed detection failure)
Error signal is detected during the failure detection operation.
• Disconnected connectors or damaged harness
• Sensors abnormal output
• Defective Double-Feed Sensors (PCB14)(PCB15)
• Defective ADF Relay Board (PCB13)
1. Check the Double-Feed Sensors (PCB14)(PCB15) and harnesses.
2. Reconnect the harness for Double-Feed Sensors (PCB14)(PCB15).
3. Replace the harnesses for Double-Feed Sensors (PCB14)(PCB15).
4. Replace the Double-Feed Sensors (PCB14)(PCB15).
5. Replace the ADF Relay Board (PCB13).
No. Type Details (Symptom, Possible Cause, Troubleshooting Procedures)
SC195-00 D Serial Number Mismatch
Serial number stored in the memory does not have the correct code.
• EEPROM defective
• BiCU (PCB1) replaced without original EEPROM
1. Check the serial number with SP5-811-002.
2. If the stored serial number is incorrect, contact your supervisor.
