Fixing a Stuck OR-330 Laminating Machine (Step-by-Step DIY Guide)

A laminating machine like the OR-330 is a simple but essential tool for office and home use. However, one common issue users face is paper getting stuck inside the roller, often caused by overheating or improper feeding.

How to clean:

• Use a knife or scraper carefully
• Remove melted plastic slowly
• Wipe with cloth if needed

⚠️ Be gentle to avoid scratching the heating surface.
