A method of extracting air from an inkjet printhead includes using an air extraction chamber connected to the printhead. The air extraction chamber comprises an air chamber, a one-way relief valve having open and closed positions used in venting of the air chamber. A compressible member is provided to vent a quantity of air from the air chamber through the one-way relief valve when it's compressed. The compressible member also expands so that a reduced air pressure is applied to the printhead when the one-way relief valve is in its closed position.
