Abstract
Abstract A replacement ribbon package for ribbon cartridge assemblies. The package comprises a Mobius Loop ribbon arranged in full fanfold fashion within a channel-shaped ribbon holder. A semirigid stripper sheet positioned between the ribbon and the base of the channel-shaped member permits the ribbon to be simply and readily stripped from the channel-shaped member once the package is inserted into the ribbon cartridge housing. A tearaway wrapper, which encircles the channel-shaped member and the ribbon serves to loosely hold the ribbon fanfold portion to prevent any creasing. The package is designed to be placed into the ribbon cartridge housing to simplify the installation operation and eliminate handling of the ribbon portion inserted into the ribbon cartridge housing. The package may be boxed or inserted within a plastic tray having a lid heat sealed to the tray flange. Instructions may be printed upon the enclosure package, the tear strip, or upon a separate insertion.
