Model Compatibility: Canon imageRUNNER 2002 and other compatible Canon imageRUNNER models Function: The Film Assembly is part of the fuser unit, which is responsible for fusing the toner to the paper. The film itself is a protective layer that prevents the toner from sticking to the fuser rollers, ensuring a clean and smooth fusing process. It also helps in the efficient transfer of toner onto the paper with the application of heat and pressure. Material: Typically made from durable, heat-resistant materials like Teflon or similar synthetic films that can withstand the high temperatures involved in the fusing process. Location: Installed within the fuser unit, near the fuser rollers and heat lamps. It interacts directly with the paper and the toner to ensure that the toner bonds securely to the page.
