Abstract: A refill station adapted to dock an ink replenishment cartridge and a printer cartridge to have its ink replenished using a flow system whereby cannula or needle interconnection with the system of the cartridges allows electronic monitoring and sequencing of the operations. The flow system has threshold valving, at least one damped route, at least one by pass route and a pump whereby ink can be cleared from the printer cartridge and be replaced by more ink from the replenishment cartridge. Pressure relief and ink quality maintenance procedures are embodied in flow system.

Abstract: An ink cartridge where, in a two part housing, there are two cannula or needle penetrable resiliently sealed ports, one port providing access to an ink supply in a collapsible reservoir defined by a blow moulded container fitted with a one way valve and the second port providing, as a waste ink recover zone, space sealed within the housing that will grow as the ink supply is drawn off in use and the ink supply reservoir collapses. Preferably the one way valve is from a dip tube in the reservoir.
