Welcome to CoffeeSnobs.
Im not an expert on the EM480 although a friend has one. Assuming the beans are fresh (less than 3 weeks from grinding will do--and please dont assume that commercial beans are fresh) two issues pop to mind--the single basket and the grinding!
1. The single basket is very hard to use. Try the double basket, fill, and either pump less water through the grounds (a "ristretto") or put the extra in the fridge for an iced coffee.
2. If this doesnt give you good cup, and the pour is still much faster than 60 ml in 30 seconds (this is a guideline only) then Sunbeam has some spacers for the grinder to make the grind finer. A search of the website here will find lots of info on this.
Along with the spacer kit you can ask for the silicon spout extension which reduces mess.
