We have various types of espresso machines, but let's pretend that we are using the one that uses ground beans to get the shots for our cappuccino. We need to measure the right quantity of ground coffee to place in the doser for one shot. To make two shots, you must go through the entire process twice.

Draw a maximum quantity of 1 scoop ( 7grams / ¼ oz. ) of ground coffee.
Fill the doser with 1 scoop (Max) of the ground coffee.
Close the cover of the ground coffee doser.
To make the shot, press the desired brew button; the selected button starts flashing, while the other switches off.
The dispensing cycle begins.
The shot will start to come out of the spout.
The shot will stop flowing automatically when the preset level is reached.
