  • Collapsible ribbon supply cartridge
    Patent number: 11285750
    Abstract: A ribbon supply cartridge for use in a card personalization machine. The ribbon supply cartridge is manually adjustable by a user before installation into the card personalization machine from a first, collapsed (or pre-use) configuration to a second, extended or open (or use) configuration. When the ribbon supply cartridge is adjusted from the first configuration to the second configuration, a distance between the supply and take-up is increased. The first, collapsed configuration may be useful for packaging or shipping the ribbon supply cartridge whereby the collapsed configuration reduces the size of the packaging or shipping box containing the ribbon supply cartridge. When the ribbon supply cartridge is to be used, the user can manually adjust the ribbon supply cartridge to the open configuration and then install the ribbon supply cartridge in the card personalization machine.
