Juicer including a juicer cartridge reader

A method comprising:

• positioning and orienting a juicer cartridge in a pressing chamber of a juicer;
• reading, by a controller, a color of temperature sensitive ink on the juicer cartridge using a sensor;
• determining that the color indicates activation of the temperature sensitive ink;
• and
• in response to determining that the color indicates activation of the temperature sensitive ink, preventing, by the controller, pressing of the juicer cartridge in the pressing chamber by a drive mechanism of the juicer.

A juicer comprising:

• a pressing chamber shaped and sized to accept a juicer cartridge;
• a drive mechanism configured to compress the juicer cartridge;
• a reader configured to read an information region of the juicer cartridge;
• and
• a controller in communication with the reader and the drive mechanism, wherein the controller is programmed to:
• retrieve user allergens;
• retrieve juicer cartridge allergens according to an output of the reader;
• prevent operation of the drive mechanism when the juicer cartridge allergens match one of the user allergens.

A method comprising:

• providing a juicer comprising:
• a pressing chamber shaped and sized to accept a juicer cartridge;
• a drive mechanism configured to compress the juicer cartridge;
• a reader configured to read an information region of the juicer cartridge;
• and
• a controller in communication with the reader and the drive mechanism positioning and orienting a juicer cartridge in a pressing chamber of a juicer;
• reading, by the controller, cartridge information from the information region of the juicer cartridge;
• and
• causing, by the controller, the drive mechanism to compress the juicer cartridge unless the cartridge information indicates any of:
