A scanning apparatus to indicate a scanning progress status includes a main body having a platen on which a document is set, a scanning module to move inside the main body and to scan the document, and an indicating light disposed integrally with the scanning module to indicate a current location of the scanning module. The pressing step includes the steps of compressing side portions of the tire between the moulding cavity walls and the outer surface of the toroidal support, concurrently with the closing step, and imposing an expansion to a radially-outer portion of the tire to bring the radially-outer portion of the tire against the walls of the moulding cavity. A merger is configured to associate the generated document annotations with positional tags based on the layout metadata, which locate the document annotations in the layout.
