Continuous Ink System

A Continuous Ink System (CIS) is a cost-effective replacement for ink-jet printer cartridges. In contrast to conventional cartridges, a CIS uses very large (about 100ml/color) ink tanks, which are connected with tubes to the printhead nozzles. The tanks can be conveniently refilled from an ink bottle - there is no need for syringes. CIS is also known as bulk ink. ---From Wikipedia, the free encyclopedia
