A method of packaging print media in combination with a printing device enables the printing device to automatically determine the type of media, and its characteristics and attributes, loaded in a media input tray. The print media package includes a pre-cut or perforated line which allows the removal of one end of the package forming a partial package exposing one end of sheets of the print media and encasing the print media. The print media is loaded in the media input tray encased in the partial package with the exposed ends of the print media sheets accessible to the printing device feed roller. The print media package includes an identifying code imprinted on an outside surface of the package located on the remaining portion of the package when the package end has been removed. The media input tray includes a sensor mounted in a location accessible to the identifying code when the print media encased in the partial package is loaded in the media input tray. When the loaded media input tray is inserted in the printing device, the sensor reads the identifying code and transmits the encoded information to the printing device control circuitry where the printing device media settings are updated.
A method for identifying a print media type loaded in a media tray of a printing device, the media tray receiving print media and having a sensor mounted therein, the print media being provided in a print media package formed of a material forming a secure package to contain and protect the print media during shipment and storage, the print media package comprising an identifying code on one of the surfaces thereof, the identifying code encoding information concerning the print media encased within the package including at least the print media type, the method comprising the steps of:
A printing device including at least one media tray for receiving print media, the print media being provided in a print media package formed of a material forming a secure package to contain and protect the print media during shipment and storage, the print media package comprising an identifying code on one of the surfaces thereof, the identifying code encoding information concerning the print media encased within the package, the media tray receiving the print media encased in a partial package obtained by removing one end of the package, the printing device comprising:
A printing device including at least one media tray for receiving print media, the print media being provided in a print media package formed of a material forming a secure package to contain and protect the print media during shipment and storage, the print media package comprising an identifying code on one of the surfaces thereof, the identifying code encoding information concerning the print media encased within the package, the media tray receiving the print media encased in a partial package obtained by removing one end of the package wherein the identifying code comprises one or more electrical conductors arranged in a predetermined pattern, the one or more electrical conductors being embedded in the surface of the package, the printing device comprising:
