ABSTRACT:
The inking mechanism of the present invention comprises one or more free-floating inking rollers which rotate within the housing of a printer cartridge between the inking brushes and the printer ribbon. While the rotation of the inking rollers is unlimited, the inking rollers are trapped between the inking brushes, the ribbon and the housing thereby limiting their freedom of movement. The free-floating aspect of the inking rollers provides a desirable pumping action against the inking brushes and the use of the inking brush, the ribbon, and the housing to trap the inking rollers eliminates the need for additional support structure.
