what is ciss
The CISS (also known as the continuous ink supply system) is compatible with many models of inkjet printers. The system delivers a continuous flow of ink to a special type of ink cartridge, through a capillary system connected to external reservoirs.hen purchased, the CISS is delivered full with ink (about 100ml for each color) and later on, when the ink runs out, you only have to buy and refill the ink for the respective color. The ink used in CISS systems is more economical and you can be sure that you will use all of it.
