Is your Ricoh copier reporting SC665-08? Don’t panic! Here’s a guide to troubleshooting the wiring.
When using a Ricoh copier, if you encounter an error code, accurately identifying the root cause is key to quickly resolving the problem. Don’t panic if the machine displays the SC665-08 error code. This problem primarily relates to the device’s internal communication connections and can be effectively resolved through targeted troubleshooting.
The core cause of the SC665-08 error is a communication error between the BCU and IOB boards. Within the Ricoh copier’s internal structure, the BCU (Basic control unit) and IOB (Input/output unit) boards are crucial components. Information between them primarily relies on a dedicated wiring cable. A problem with this wiring cable can disrupt or malfunction communication between the two boards, triggering the SC665-08 error.
KBT technicians’ years of maintenance experience have shown that wiring issues are the primary cause of this problem. For example, a defective cable, poor connector contact, or the use of an inappropriate cable (such as using a scanner cable with the IOB board) can cause a communication error, resulting in the SC665-08 error.
The troubleshooting and resolution steps for this problem are simple and are as follows:
Step 1:
Check whether the cable is loose or improperly installed. First, turn off the copier power. Then, locate the cable connecting the BCU board and the IOB board and check that the connectors at both ends are firmly seated in their corresponding slots. Ensure that the cable is not loose or partially inserted. If a loose connection is found, reconnect the cable and ensure it is properly seated before restarting the machine to test whether the error message recurs.
Step 2:
Clean the metal contacts on the cable connector. If the SC665-08 error message persists after the cable is properly connected, unplug the cable and gently wipe the metal contacts on both ends with a clean eraser to remove any surface oxide, dust, or stains. After cleaning, reinsert the cable into the connector to ensure proper contact, then restart the machine and test again.
Step 3:
Replace the cable. If the problem persists after the above two steps, the cable itself is likely damaged (e.g., internal wiring is broken, short-circuited, etc.). In this case, simply replace it with a new, compatible, dedicated cable, correctly connect the BCU and IOB boards, and restart the copier. This will usually resolve the SC665-08 error.
It is important to note that when troubleshooting and replacing the cable, always turn off the copier to avoid damage to the machine or risk of electric shock. When purchasing a new cable, choose an original or high-quality compatible cable that matches the model to avoid recurring similar problems due to cable mismatch.
With these simple troubleshooting and troubleshooting steps, you can easily resolve the error on your Ricoh SC665-08 copier and restore normal operation.
