Error Name/Error Condition/Major Cause/Solution
SBU (PCB3) Communication Error
• The machine cannot detect that the Scanner Carriage is connected.
• The machine cannot communicate with the Scanner Carriage, or the
communication data is incorrect.
• The configuration of FPGA is not completed.
Error detection timing: At the time of turning on the scanner (when the main
power is turned ON or when the machine returns from energy saving mode)
• Scanner Carriage defective
• BiCU (PCB16) defective
• IOB (PCB17) defective
• Harness defective
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. Reconnect the following connectors.
• Scanner Carriage – BiCU (PCB16) connector
• BiCU (PCB16) – IOB (PCB17) connector
2. Scanner carriage defective
Replace the scanner carriage.
3. BiCU (PCB16) defective
Replace the BiCU (PCB16).
4. IOB (PCB17) defective
Replace the IOB (PCB17).
5. Harness defective
Replace the following harnesses.
• Scanner Carriage – BiCU (PCB16) harness
• BiCU (PCB16) – IOB (PCB17) harness
