Solutions

Quick diagnosis

If the error appears immediately after turning on, listen for a motor noise trapped in the upper section (under the glass). If the carriage does not move upon power-up, the F-04 error is confirmed.

Step-by-step solution

  1. Disconnect the equipment and wait 2 minutes.
  2. Reconnect the device and watch the panel. If the carriage attempts movement, gently assist if a minor jam is felt.
  3. Ensure there is no direct sunlight hitting the scanner's home position sensor.
  4. If the error persists, attempt a firmware update via the official manufacturer website.

Prevention and maintenance

Keep the glass clean and avoid placing heavy objects on the top lid, as they can misalign the carriage. Perform a weekly power cycle to avoid software error buildup.

When to call a technician

If the scanner motor emits grinding noises or the carriage never initiates movement, the stepper motor or the drive belt may be damaged, requiring professional repair.
