20 lb Taped to Core Copier Paper

20lb Taped to Core Paper. 3 inch core roll that is attached to the core (at the end of the roll). One process used in toner based large format laser paper copiers, scanners and printers that acted as a break or a stop mechanism for the machine. As it got close to the taped end of the roll the printer would sense the rolls end and stop the printing, in turn, not continuing to run, run, run with no 20lb printing media available.
