Why did my cup overflow with my Ninja COFFEE BAR CF091 Coffee Maker?

If your cup, travel mug, or carafe overflowed while using the Ninja Coffee Maker, the container may not have been empty before brewing. Ensure you're using the correct size: at least a 12 oz cup for the cup size, 14 oz for the tall cup, 16 oz for the travel mug, and 20 oz for the XL travel mug.
