Abstract: A printer comprising: a printhead having an ink inlet and an ink outlet; an ink chamber for supplying ink to the printhead; an upstream ink line interconnecting an outlet port of the ink chamber and the ink inlet; a downstream ink line connected to the ink outlet; and a first air accumulator communicating with the downstream ink line. The first air accumulator is configured for dampening ink pressure pulses in the printhead during printing.

Abstract: A system for venting gas at ink containers which supply inks to a multi-channel inkjet printhead is provided having a plurality of ink containers for supplying fluids to a printhead having a plurality of ink channels, and a gas vent assembly having a plurality of gas vents. Each ink container has an ink port connected to a corresponding one of the ink channels of the printhead and a gas port. Each gas vent is connected to a corresponding one of the gas ports of the ink containers. The gas vents of the gas vent assembly are in fluid communication with the external atmosphere.

Abstract: An inkjet printer includes: an inkjet printhead; an ink reservoir containing a supply of ink; and a pressure-regulating chamber for maintaining ink contained therein at a predetermined first level. The chamber includes: an inlet port connected to the ink reservoir via an ink supply line; an outlet port connected to an ink inlet of the printhead via an upstream ink line; an air vent open to atmosphere; and a float valve for maintaining the predetermined first level of ink. The float valve includes: an arm pivotally mounted about a pivot; a float mounted at one end of the arm; and a valve stem attached to the arm, said valve stem having a valve head for closure of a valve seat, the valve seat being positioned at the inlet port of the pressure-regulating chamber.

Abstract: A system for sensing a predetermined pressure change at a port of a liquid container for supplying liquid to a printer, the system having a liquid delivery apparatus connected to a liquid container via a fluid line and a sensing arrangement connected to the fluid line, wherein the liquid container has an internal fluid pressure changing member configured so that contact with liquid being delivered by the liquid delivery apparatus causes the predetermined pressure change in the fluid line, and the sensing arrangement is configured to sense the predetermined pressure change in the fluid line.
