The anti-static technology will work best for about 60 grinding cycles using light or medium roast coffee before it needs to be cleaned to continue to operate at its peak performance. Please note, using dark or oily roast coffee will require maintenance more frequently in order to prevent the Opus from clogging.
To clean, remove the catch cup and use the Fellow cleaning brush (or another cleaning brush such as a clean makeup brush or a clean paint brush) and “swipe” around the inside of the exit chute (where the coffee grounds come out). This will clean the chute and help the anti-static mechanisms work well.
