Abstract
A sensor hub for a print ribbon supply roll includes a sleeve shaped to attach to the roll core of the print ribbon supply roll, a pin-receiving plate secured to the sleeve and including a plurality of apertures, and a plurality of pins permanently secured in selected ones of the apertures. The pins are arranged in the apertures according to a print ribbon type to thereby identify the print ribbon type. The sleeve, pin-receiving plate and pins are preferably molded in a single step operation, thereby decreasing manufacturing time and reducing manufacturing costs. By molding the sleeve and pin-receiving plate around the pins, the pins can be permanently secured in the apertures of the pin-receiving plate, and the mold cavity can be constructed so as to eliminate susceptibility to human error.
