Abstract
Colorant transfer, involving a colorant supply, and impeding colorant from exiting the colorant supply, a motion device, and providing a passage out of the colorant supply.
Claims15
A colorant transfer system, comprising:
- a colorant supply to supply colorant contained in the supply to a colorant delivery device, the colorant supply having a first state wherein the colorant is impeded from exiting the colorant supply;
- an actuator to provide a passage from the colorant supply to the colorant delivery device;
- and
- a control circuit to:
- validate an authentication code and, if the authentication code is validated, instruct the actuator to provide the passage from the colorant supply to the colorant delivery device.
2 more elements
A method of activating a colorant transfer system, the colorant transfer system comprising a control circuit, a motion device and a colorant supply, the method comprising:
- impeding colorant from exiting the colorant supply;
- entering an authentication code into the control circuit;
- validating the authentication code with the control circuit;
- with the control circuit, signaling an actuation instruction to the motion device;
- triggering a mechanical actuation with the motion device;
- and
- via the actuation, providing a passage from the colorant supply to a colorant delivery device.
4 more elements
A colorant transfer system, comprising:
- a colorant delivery device to supply colorant to media;
- a colorant supply to supply colorant to the colorant delivery device;
- a motion device;
- and
- a control circuit to
- validate an authentication code, and
- upon validating the authentication code, signal the motion device to automatically establish passage from the colorant supply to the colorant delivery device.
