Solutions

Diagnóstico rápido

Error C4200 appears at start-up. If the printer freezes during warm-up, the sensor is likely not detecting the required heat. Do not touch the fuser area immediately after a shutdown, as it can remain extremely hot for a long period.

Solución paso a paso

  1. Cool Down: Turn off the unit and allow the fuser area to cool for at least 20 minutes before inspecting.
  2. Clear Obstructions: Open the rear door and check for paper scraps or debris trapped in the fuser rollers.
  3. Power Test: After clearing any debris, restart the printer to see if it finishes the warm-up cycle.

Prevención y mantenimiento

Maintain stable power, use original toner, and avoid thick staples. When the device reaches the duty cycle limit, the fuser should be replaced as part of routine maintenance.

Cuándo llamar a un técnico

If the error persists after checking for obstructions, the thermistor or internal heating lamp has failed. This requires professional technician intervention.
