Abstract
A fluid cartridge for an inkjet printer includes an inner reservoir containing a printing fluid. The reservoir includes walls enclosing an internal space having a variable volume for storage of the printing fluid and a port for dispensing the printing liquid. The reservoir includes a rigid framework and one or more elastically deformable sections. The cartridge further includes an outlet for connection to the printer, an outer housing in which the reservoir is housed, an electronic storage device configured to store data relating to the contents of the cartridge, and at least one electrical contact associated with the electronic storage device and provided on a substrate. The reservoir provides a reduction in pressure of the internal space whereby the equilibrium pressure difference between the internal space and the surrounding atmosphere increases substantially monotonically in magnitude as liquid is dispensed.
