Solutions

Quick Diagnosis

Does the scanner make a thumping sound when you turn the machine on? If so, the carriage is likely physically obstructed. If there is no sound, the issue might be an internal cable connection or software deadlock.

Step-by-Step Solution

  1. Disconnect the power cord fully.
  2. Gently move the scanner assembly to see if it glides freely.
  3. Clean the optical path with a lint-free cloth to ensure the scanner sensor is not triggered by dust.
  4. Power up the device again to trigger a fresh initialization scan.

Prevention and Maintenance

Do not press down hard on the scanner glass, as this can force the carriage off its track. Routine cleaning keeps the path clear and prevents dust-related sensor errors.

When to Call a Technician

If the machine continues to report the 30-3 error and makes loud noises from the scanning area, it indicates the motor or the internal timing belt requires replacement.
