Solutions

Diagnóstico rápido

If the machine displays C3100 and you hear grinding noises from the top section, it is highly likely that the scanner carriage is physically jammed.

Solución paso a paso

  1. Power off: Shut down the device from the main power switch.
  2. Physical inspection: Lift the document cover and check for debris or obstructions along the glass path.
  3. Manual reset: Gently move the scanner carriage assembly along its rail to ensure it moves smoothly without resistance.
  4. Initialization: Close the cover and turn on the machine to let it run its calibration.

Prevención y mantenimiento

Keep the scanner glass clean with a soft, dry cloth. Never place heavy stacks of paper on top of the ADF (Automatic Document Feeder) to prevent stress on the scanner assembly.

Cuándo llamar a un técnico

If the grinding noise persists or the carriage fails to move after a physical check, the motor or scanner control board may require replacement by professional staff.

It is a sign of a physical jam that could damage the motor if the machine is forced to operate.

Always use genuine TK-6325 toner to protect the machine's internal optics and components.

No, never apply oil; this will capture dust and create a thick sludge that stops the scanner carriage.
