SC No.	Type	Error Name/Error Condition/Major Cause/Solution
SC621-01	D	Finisher communication error
SC621-02	D	Mailbox communication error
		When the communication line has opened and the machine is in a normal communication state, it has received a break signal from a connected device. There is not any response within 100 ms after the data frame transmission, and retries have failed with timeout error for 3 times in a row. When changing the baud rate after program downloading starts, the machine has failed to detect the break signal of the finisher or has failed to detect that the break has been cleared.
		Connection error between finisher and main machine. The finisher-related firmware is not installed properly. The engine firmware is not installed properly. Finisher control board defective. BCU, or IOB defective Communication error caused by electrostatic noise
		Check if the SC occurs by turning the main 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. Check if all connectors in the finisher/mailbox are connected securely. Reconnect the connectors if they are disconnected, or loose. Update the firmware to the latest version. Check all harnesses in the mailbox or finisher. Replace any harness that is damaged. Replace the BCU, or IOB. Replace the controller board of the finisher or the mailbox.
