Markem‑Imaje SmartLase 110i is a compact CO₂ laser coder rated up to 30 W (or 10 W in the si variant) with IP56 protection and a 9.3 µm wavelength, used for high‑speed package coding. Common failures include power supply voltage drops or ripple that trigger “power fault” errors, laser tube burnout after prolonged use, galvo head misalignment or motor stall, and controller board overheating due to inadequate ventilation. Begin troubleshooting by verifying the input voltage and inspecting the power module for signs of burn‑in; check the laser tube’s electrical contacts and optical path for debris or damage; and review any error codes displayed on the UI panel while performing a visual inspection of the galvo head and cooling fan operation.[oss-gpt-20b]
