Possible Causes
Dirty barcode scanner window, Damaged or misaligned barcode LED/sensor, Cracked or scratched scanner lens, Faulty wiring between scanner and control board
How to Fix / Troubleshooting
Safety first: Unplug the machine before cleaning inside the brew head.
- Clean scanner window: Open the brew head and locate the small transparent window where the barcode is read. Wipe it gently with a soft, lint-free cloth slightly dampened with water. Do not use abrasive cleaners.
- Check T DISCs: Inspect the barcode on several T DISCs. Ensure they are not scratched, wrinkled, or covered with coffee residue.
- Test with service disc: Insert the yellow/orange service T DISC and see if the machine recognizes it. If not, the scanner may be faulty.
- Avoid forcing the lid: Misalignment can worsen if the lid is slammed shut.
- If cleaning does not help: The barcode reader module or its cable likely needs replacement, which should be performed by a technician.
