SC645-01 C Toner Supply: ID Chip Communication Error (K)
SC645-02 C Toner Supply: ID Chip Communication Error (M)
SC645-03 C Toner Supply: ID Chip Communication Error (C)
SC645-04 C Toner Supply: ID Chip Communication Error (Y)
A communication error is received during EEPROM communication and the
machine fails to recover even if the power is switched OFF and back ON for
tagging.
Connection error between the toner ID Chip (PCB3-PCB6) and the Toner
Bottle Sensor Board (PCB7).
1. Clean the contact part of the toner bottle ID chip (PCB3-PCB6) and check
that the pins of the Toner Bottle Sensor Board (PCB7) connector are not
bent. If any of the pins are bent, replace the Toner Bottle Sensor Board
(PCB7).
2. Reconnect the connectors between the BiCU (PCB1) and Toner Bottle
Sensor Board (PCB7).
3. Replace the harness between the BiCU (PCB1) and Toner Bottle Sensor
Board (PCB7).
4. Replace the BiCU (PCB1).

SC650-01 C Remote Service Modem Communication Error (Dialup Authentication
Failure)
• An error related to communication (dialup connection, modem board etc.)
using the RC Gate Type M was detected or an error that prevents RC
Gate operation was detected at power on.
• Displayed only when an error is detected while RC Gate is operating.
• SC is not issued if an error occurs during RC Gate installation (because it
can be referenced using SP).
• SP settings invalid
• Modem connector disconnected
• Modem board disconnected
• Wireless LAN card disconnected
Check the following SPs.
• SP5-816-156 (Remote Service: Dial Up User Name)
• SP5-816-157 (Remote Service: Dial Up Password)
