The K3 Elite is Compak's doser model. Ground coffee flows into the "doser" on the front of the machine, and you pull a level to push grounds out. In commercial applications, the doser is often kept full of grounds, in which case the doser should push out the same quantity of grounds with each pull of the lever. But, in home applications you'll probably just be grinding enough coffee for a shot or two of espresso, so in this case you can't rely on the doser to push out a consistent amount of coffee. What a doser will do at home, though, is break up clumps. Static in the grinds causes them to clump together at finer grind levels, and these clumps can be a headache when trying to achieve a perfect espresso. Clumps in the puck can lead to channeling and other extraction problems. The action of the doser hitting the grinds tends to break up the clumps.
