Regular cleaning of the Fusion Pro engraver will result in a longer service life of the engraver and less down time. Additionally, regular cleaning of the Fusion Pro engraver can mitigate the risk of flare-ups and other thermal events. A mild household cleaner or degreaser can be used to clean all hard surfaces of the engraver except for the optics. Optics should be cleaned using Epilog Laser branded Multi-Coated Filter and Lens cleaner, reagent grade acetone, or a similar high-quality optics cleaning solution.
