Common causes

  • 1Bus communication error: Data packet loss between the main logic board and scanner.
  • 2Corrupted firmware: Software data damage due to power interruption.
  • 3Unseated scanner cable: Loose flex cable due to machine vibrations.
  • 4Electrical noise: Voltage interference affecting logic signal transmission.

Solutions

Diagnóstico rápido

If the error appears immediately after power-on, it suggests a logic connection error. Often, the scanner unit remains stationary or the display hangs on the loading screen. This is a typical internal communication problem that can usually be fixed with a simple power cycle.

Solución paso a paso

  1. Hard reset: Turn off the device, unplug it for 60 seconds, and power it back up to reset internal communication.
  2. Check cables: Ensure network and internal flat cables to the main board are properly seated and undamaged.
  3. Firmware update: Check if there is a pending firmware patch designed to address internal communication bugs.
  4. Network reset: If the issue persists, restore network factory defaults via the system menu.

Prevención y mantenimiento

Ensure the device is connected to a reliable power source to prevent static buildup that could degrade board components. Do not shut down the device while it is performing firmware updates or high-priority scanning tasks.

Cuándo llamar a un técnico

If the reset does not fix the problem, it might indicate a physical failure on the system board (SYS board) or a disconnected internal scanner harness that requires technician intervention.

Frequently asked questions

The F101 error indicates a failure in communication between the main motherboard and the scanner unit, preventing the machine from starting scanning or copying operations.

Yes, as this error disables key features like scanning and printing, making your device unusable until the logic connection is re-established.

We recommend using genuine T-FC355 toner to prevent potential image sensor conflicts that can occasionally mirror logic board errors.

Keep your firmware updated and ensure the device is plugged into a surge protector to prevent electrical interference affecting the board.
