Abstract: The present disclosure relates to the programming an identifier, such as an RFID tag on a sheet of print media. In the event of an unsuccessfully programmed tag, it may be reprogrammed onto the same or subsequent sheet of print media. A determination may also be made as to whether or not the reprogramming on the same or a subsequent sheet of media requires shifting of the programming originally intended for the same or subsequent sheet of media. In addition, the reprogramming may take place on print media at the completion of a particular print job.

Abstract: A dart flight stem comprises a metal root portion attached by screw thread to a dart barrel. A flight-holding portion is mounted on the root portion for rotation about the longitudinal axis of the flight stem. A shaft extends axially from the flight-holding portion into a complementary bore extending axially from the adjoining end of the root portion. The shaft has a circumferential groove and the peripheral metal wall in the root portion is locally crimped to form radially inwardly peripheral projections in the circumferential groove around the shaft, whereby the flight holding portion is held captive on said root portion. The dart flight stem made by a method of selecting root portion with screw threads at the front end for attachment to a dart barrel. A flight holding portion is mounted on the rear end of the root portion. An axial blind bore is provided in the root portion to establish a rotating fit with a shaft on the flight holding portion.
