Abstract
Methods are provided for operating a web medium supply for a printer and or operating a printer having a web medium supply to which any of a plurality of different cores can be mounted, each core having a web. In one aspect, a core data condition is detected indicating that an automatic core data acquisition process is to be executed and conditions are sensed from which a difference in the rotational positions of a first engaged surface at a first end of the core and a second engaged surface at a second end of the core can be determined. Data regarding the web on the core is determined based upon the sensed conditions.

A method for operating a web medium supply for a printer to which any of a plurality of different cores can be mounted, each core having a web, the method comprising:
- detecting a core data condition indicating that an automatic core data acquisition process is to be executed;
- sensing conditions from which a difference in the rotational positions of a first engaged surface at a first end of the core and a second engaged surface at a second end of the core can be determined by sensing a first detectable feature on the first core mounting having a known rotational position with respect to a first engagement surface that corresponds to and is proximate to the first engaged surface and sensing a second detectable feature on the second core mounting having a known rotational position with respect to a second engagement surface that corresponds to and is proximate to the second engaged surface;
- and
- determining data regarding the web on the core based upon the sensed conditions by first determining a rotational position of the first detectable feature by rotating the core when the core is loaded between the first core mounting and the second core mounting and sensing during such rotation the first detectable feature and the second detectable features and determining the rotational positions of the first core mounting and the second core mounting based upon when, during rotation, the first detectable feature and second detectable features are sensed.
A method for operating a web medium supply for a printer to which any of a plurality of different cores can be mounted, each core having a web, the method comprising:
- detecting a core data condition indicating that an automatic core data acquisition process is to be executed;
- sensing conditions from which a difference in the rotational positions of a first engaged surface at a first end of the core and a second engaged surface at a second end of the core can be determined using a first core mounting having a first detectable feature and a second core mounting having a second detectable feature that are indicative, respectively of the rotational positions of the first engaged surface of the core and the second engaged surface of the core;
- and
- determining data regarding the web on the core based upon the sensed conditions.
