Scanner communication error (FPGA)
• Cannot communicate with scanning device (FPGA), or communication is
abnormal
• Cannot complete FPGA configuration
Error detection timing;
• During scanner startup (main power was turned on or the machine returned
from energy saving mode)
• During a scan
• BiCU (PCB16) 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. BiCU (PCB16) defective
Replace the BiCU (PCB16).

Scanner communication error (FPGA)
Error occured while initializing DDR-PHY and/or TRAINING status confirmation.
Error detection timing;
• When the machine was turned on or the machine returned from energy saving
mode
• BiCU (PCB16) defective
• DRAM device 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 all connectors.
