SC623-00 D Paper bank 2 communication error for LCIT RT3030 (D696)
During superposition of single bank - double bank, double bank - side
LICT, and LCIT - side LCIT,
1. When the upper bank side recognizes the lower bank, the break of
the lower bank is not canceled within the specified time (ms.).
2. After the upper bank side recognizes the lower bank, there is no
ACK within the specified time (ms.) after transmission of a data
frame to the lower bank, and a timeout error occurs for 3 times
consecutively even if retransmission is performed
• Bank control board error
• Connector disconnected
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.
1. Check if all connectors in the Paper Feed Unit PB3160 or LCIT
PB3170/PB3230 are connected securely. Reconnect the
connectors if they are disconnected, or loose.
2. Check the harness in the Paper Feed Unit PB3160 or LCIT PB3170/
PB3230. Replace the harness if it is disconnected, or damaged.
3. Check if there are any signs of a short circuit on Paper Transport
IOB, or side LCIT. If there are any defects, replace the board.
