The Continues Ink System (CIS) consists of a high-capacity ink reservoir 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. This reservoir allows printing for an extended period of time without running out. The red line on the reservoir indicates time to refill. Each CIS comes complete with easy-to-follow instructions, 165 ml ink of each color, and all accessories needed to successfully use the system. The included CIS 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! Eliminate costly replacement cartridges. |
