ABSTRACT:
A re-inkable ribbon cartridge for impact computer printers featuring duel re-inking rollers of sufficiently small diameter so as to insure rapid rotational speed, ensuring that centrifugal force will cause the ink to migrate to the outer roller surface. A single re-inking port axially positioned over each of the two rollers, permitting rapid, single-point re-inking, when needed.
A radially rotational plate on which the blotting rollers are positioned which by spring tension moves so as to keep the ribbon taut.
A two-member parallel dam with the surface of each dam component at over-lapping elevations so as to provide two surfaces to act as an unfurling structure.
