You will be printing in minutes. - No Leaking or Clogging - Pre-Assembled - Environmentally Friendly The CIS(Continuous Ink System) consists of a high-capacity ink reservoir (same as using between 8 ~ 10 ink cartridges per color) that is attached to a cartridge via secure tubing. The tubing acts as a vacuum to extract ink from the reservoir and keep the cartridge full of ink. Because of the large reservoir capacity, you can print for an extended period of time without running low right away. There is a red line on the reservoir to indicate when it is time to refill. Each CIS comes complete with easy-to-follow instructions, ink, and all accessories needed to successfully use the system. The included UCI cartridges have a permanent smart chip already installed, which will automatically reset itself when your printer power is turned off (for 5 seconds) and turned back on. No mess! No leaking! < Call Service's Provided >You can check the contact information in seller help page - For contact point, please go to gigablockshop store front in amazon.
