Abstract
Bi-level cartridge for an endless printer ribbon has superposed upper and lower compartments with a ribbon stuffing feed means located in each compartment. The ribbon is guided so that it travels once through each of the compartments for each pass that it makes past a printing station. The feed means for each compartment are coaxial and keyed together so they can be driven by the printer's drive member. To facilitate threading and stuffing of the cartridge, an idler roller portion for one of the feed means is selectively movable into or out of biased engagement with its driven roller portion.
