In order to program the cup size of a Pixie machine, the individual first needs to push down the rectangular black power button on the front of the machine to turn it on.
As soon as the lights have stopped blinking, the user can insert their capsule that is compatible with Nespresso machines into the top of the machine and put their appropriate sized cup underneath of the valve.
They then need to press down either the espresso or lungo button, depending on which one they are interested in programming, and keep pressure on it until the level of the coffee has reached their desired amount.
Once they let go of the button, the machine will remember the amount of coffee that was poured and will program that amount to be the new standard for that button. So next time that they want a cup of coffee, all they need to do is press either the espresso or lungo button, depending on which one has been programmed, and the machine will automatically pour that same amount.
