Claims15
A print device comprising:
- a consumable component comprising a human-indiscernible hardware-based identifier;
- and
- a sensor to read the human-indiscernible hardware-based identifier.
A method comprising:
- detecting a human-indiscernible hardware-based identifier arranged on a consumable component of a print device using a sensor of the print device;
- and
- transmitting signals representative of the detected human-indiscernible hardware-based identifier to a processor of the print device.
A print device comprising:
- an organic photoconductor (OPC) drum comprising a unique human-indiscernible hardware-based identifier arranged in a peripheral portion of the OPC drum;
- an intermediate transfer belt to receive a latent image from the peripheral portion of the OPC drum, the latent image corresponding to the human-indiscernible hardware-based identifier;
- and
- a sensor to read the latent image and enable authentication of the OPC drum based thereon.
