Abstract

A method of operating a blender having a rotatable cutting blade in a food preparation chamber includes providing a sensing light assembly, generating at least one sensing light beam below the food preparation chamber, inserting a cup containing food to be blended into the food preparation chamber, generating an error signal if a foreign object crosses the sensing light beam, and preventing or stopping rotation of the cutting blade in response to the error signal.
