Solutions

Quick Diagnosis

If the error persists after a restart and the light never illuminates during startup, it is a lamp power failure. If it flashes, it is a communication error between the light sensor and the controller.

Step-by-Step Solution

  1. Disconnect the device from power completely for 2 minutes.
  2. Ensure the printer is plugged into a wall outlet, not a power strip, for better power stability.
  3. Check for any internal dust on the scanning lamp.
  4. Power back on and look closely at the glass to check if the light activates.

Prevention and Maintenance

Clean the scanner glass weekly to remove toner dust and fingerprints. Regularly check for firmware updates, as they often include scanner stability improvements.

When to Call a Technician

If the lamp light is physically broken or does not come on after a full reset, the scanner module needs replacement by a service technician.
