The NEW CISS (Continuous Ink Supply System) provides significant cost and time savings to the high volume ink user. The CISS provides a continuous supply of ink to the printer without the need to replace cartridges. This ingenious ink flow system works by using a vacuum seal which prevents leakage and loss of ink supply to the cartridges. The NEW CISS does not require the chips to be reset on the cartridge therefore no chip re-setter is required.
