Abstract
There is provided a print apparatus and a media roll for the print apparatus, comprising a media identifier located on an end of a core section of the media roll. A type of media loaded into the print apparatus is determined by sensing the media identifier on the media roll using a non-contact sensor to scan the end of the core section.
Claims15
A printing system, comprising:
- a print engine wherein print parameters are set;
- a media holder to receive a media roll having a media section and a core section, the core section comprising a media identifier associated to a type of media;
- and
- a reader comprising a non-contact sensor configured to scan the core section of the media roll and to receive the media identifier;
- wherein the reader further comprises a controller to receive the media identifier and a wireless transmitter to issue an identification signal associated to the media identifier to the print engine and wherein the print engine is to set the print parameters based on the identification signal.

A method of identifying a media roll for use in a printer, comprising:
- providing the media roll having a core section and a media section, the core section comprising a media identifier located on an end of the core section and disposed annularly about an axis of rotation of the core section;
- sensing the media identifier using a non-contact sensor provided by a reader to scan the end of the core section;
- determining a type of media of the media section using the sensed media identifier;
- and
- sending an identification signal associated to the media identifier to a print engine.
2 more elements
A reader for a print apparatus, the reader comprising:
- a sensor to read from a media roll a media identifier;
- a controller to receive from the sensor the media identifier, the controller comprising a transmitter to issue an identification signal associated to the media identifier to the print apparatus;
- wherein the sensor is a non-contact sensor and the transmitter is a wireless transmitter.
