Abstract

This invention proposes a media (e.g. paper) spool capable of electronically storing the properties and/or characteristics of the print media wrapped around it. The system would be made up of an RFID (Radio Frequency Identification) tag located on/in the spool and a reader circuit board located within the machine such that the RFID tag can be activated and communicated with.

Smart Media Roll For Automated Machine Setup

This invention proposes a media (e.g. paper) spool capable of electronically storing the properties and/or characteristics of the print media wrapped around it.  The system would be made up of an RFID (Radio Frequency Identification) tag located on/in the spool and a reader circuit board located within the machine such that the RFID tag can be activated and communicated with.

An RFID system is ideal for this application because spooled media turns, which would make the implementation of a hard-wired system difficult.  A machine using this technology could identify the media as genuine product, its length, width, weight and type among other characteristics.  This could be very convenient for both the customer and the manufacturer.

How to make it work:

 

FIGURE #1

This figure shows an embodiment where a tag is placed on the end of a media roll spool, and a reader antenna (part of the printer - not the media roll) is mounted such that it is parallel with the plane created by the tag.  This configuration can be designed such that enough magnetic flux is created by the reader antenna such that the tag on the media roll can be communicated with 100 % of the time as the media roll rotates.   These conditions would allow for the reader to have 100% visibility of the tag.  

With this system the machine can perform all the functions typically associated with a Customer Replaceable Unit (CRU).  These could include (but not be limited to): providing feedback on the paper volume (paper remaining on roll), media type, weight, and width, as well as marketing information such as region and market identification.  In addition to these parameters, information relevant to the optimiz...
