What About Code Sc665-02 For My Machine ?????

SC665-02 indicates a communication failure between the BCU (Board Control Unit) and the Imaging IOB (Image Input/Output Board). This means these components aren't communicating properly.

Troubleshooting Steps:

Check Toner Bottles:

Remove toner bottles one by one. If the code disappears when a specific bottle is removed, replace that bottle.

Check Development Unit:

Remove the development unit. If the code disappears, replace the development unit.

Check Ribbon Cables (FFCs):

Inspect the flat flexible cables (FFCs) that connect the BCU, Imaging IOB, and Transport IOB (if applicable). Look for damage, loose connections, or debris. Reconnect any loose cables.

Replace Boards (if necessary):

If the above steps don't resolve the issue, you may need to replace one or more boards:

BCU (Board Control Unit)

Imaging IOB (Image Input/Output Board)

Transport IOB (if applicable)

Recommendations:

Consult Service Manual: Refer to the Ricoh MP C6003 service manual for detailed instructions and diagrams.

Contact Ricoh Support: Seek assistance from Ricoh's technical support team for specific guidance and potential warranty coverage.

Engage a Certified Technician: For complex repairs or board replacements, consider hiring a certified Ricoh technician to ensure proper diagnosis and resolution.

Additional Considerations:

Error Code Persistence: If the error code persists after attempting these steps, further troubleshooting by a qualified technician is necessary.

Power Cycle: In some cases, a simple power cycle (turning the machine off and on) may temporarily clear the error, but it's essential to address the underlying cause.

Remember:

Always exercise caution when working with electronic devices.

Disconnect the machine from power before attempting any repairs or component replacements.

Using genuine Ricoh parts is recommended for optimal performance and compatibility.
