Solutions

Diagnóstico rápido

The U4 error is triggered when the scanner detects a blockage in the ADF transport path. Symptoms include the scanner stopping mid-page and a flashing alert light on the operation panel. Ensure no small shreds of paper remain in the path.

Solución paso a paso

  1. Power off the unit and disconnect it from the power source for safety.
  2. Open the ADF cover by activating the side release lever.
  3. Carefully remove any jammed documents or paper debris found inside.
  4. Clean the sensor area using a dry, lint-free cloth to ensure the optical path is unobstructed.
  5. Close the ADF cover securely and restart the scanner to clear the error state.

Prevención y mantenimiento

Clean the rubber rollers monthly using official cleaning fluid to maintain grip and prevent slippage. Avoid feeding stapled or damaged documents through the scanner. Ensure the device is stored in a clean environment to reduce dust accumulation inside the sensor array.

Cuándo llamar a un técnico

If the U4 error persists after cleaning and clearing the paper path, there may be a failure in the document exit sensor or the logic board. In this case, contact professional support for hardware diagnostics.
