6300 Series Maintenance Manual121.5 Consumables1.5.1 RibbonsThe 6300 Series uses a ribbon cartridge that is incompatible with some previous Tally products(Reference Tally Specification 613184). This cartridge is designed to significantly increase thelife of the ribbon, reducing the cost of ownership of the product. This ribbon also has increasedreliability due to the incorporation of ribbon fault detect and skip over weld. The ribbon alsomaintains much more uniform print density over its useful life due to the incorporation of a pumpre-inking system. This system supplies ink to the ribbon based on the amount of printing that hastaken place, and separates the re-inking and ribbon motion functions. This results in morecontrollable and predictable re-inking, with attendant improvements in print quality and reliability.The 6312 may use the 60 or 250 million character pump re-inking ribbon cartridges. The 40million non re-inking ribbon may also be used.The 6306 uses a standard 40 million character non re-inking ribbon cartridge without the skip overweld feature.All cartridges are designed for easy access and loading.
