How does a Keurig K-Duo coffee maker work?

A Keurig K-Duo coffee maker is a coffee machine that brews both single cups and full carafes of coffee. It has a water reservoir that holds enough water to brew multiple cups of coffee, and it has a coffee filter that can be used with either ground coffee or K-Cups.

To brew a single cup of coffee, the user inserts a K-Cup into the coffee machine and presses the brew button. To brew a full carafe of coffee, the user inserts a coffee filter into the coffee machine and adds ground coffee to the filter. The user then presses the brew button and the Keurig K-Duo coffee maker brews a full carafe of coffee.
