  • 2Firmware incompatibility with current office network protocols.
  • 3Failure in the internal network controller cache.
  • 4Overloaded printer buffer due to oversized document processing.

Solutions

Diagnóstico rápido

The C-9402 error often occurs during network scanning or printing complex files. The unit freezes while processing, then displays the error. If your office network is functioning, the issue lies within the machine's internal processing logic or NIC firmware.

Solución paso a paso

  1. Reset the network settings via the Utility menu (Network > TCP/IP Settings).
  2. Update the firmware to the latest version to ensure NIC stability and compatibility.
  3. Test with a new Ethernet cable to rule out physical infrastructure issues.
  4. Perform a soft reset by powering down the unit and restoring factory network defaults.

Prevención y mantenimiento

Use an Uninterruptible Power Supply (UPS) to protect the board from power surges. Regularly check for firmware updates on the official portal. Configure firewall filters to prevent malicious packets from overloading the machine's buffer.

Cuándo llamar a un técnico

If resetting network settings and changing cables does not resolve the scanning issue, the internal MFP controller board may be faulty. Professional replacement is necessary at this stage.
