A fluid distribution system for a printhead, the system having a fluid container fluidically interconnected with the printhead via a closed fluid flow loop, a gas vent on the closed loop and a multi-path valve on the closed loop for selectively allowing venting of gas in the closed loop via the gas vent.

Fluid distribution system having multi-path valve for gas venting

A fluid distribution system for a printhead, the system having a fluid container fluidically interconnected with the printhead via a closed fluid flow loop, a bypass fluid path bypassing the printhead on the closed loop, a gas vent on the closed loop and a four-way valve on the closed loop for selectively allowing fluid flow along the closed loop via the printhead and the bypass path and venting of gas in the closed loop via the gas vent.

Fluid distribution system having four-way valve

A printing system having a media width printhead, a plurality of fluid containers fluidically interconnected with the printhead via a respective plurality of fluid tubes each defining an individual closed fluid flow loop, a first multi-channel valve arrangement for selectively allowing fluid flow along each closed loop via the printhead by selectively moving a pinch element into and out of pinching contact with the fluid tubes so as to respectively block and allow fluid flow through the fluid tubes, a plurality of gas vents, each gas vent being associated with a respective one of the closed loops and a second multi-channel valve arrangement for selectively allowing venting of gas in each closed loop via the gas vents.

Printing system having valved ink and gas distribution for printhead

A fluid container having a body for containing fluid, a fluid outlet on a first wall of the body at which the contained fluid exits the body and a filter arranged within the body adjoining the first wall so that the contained fluid passes through the filter before exiting the outlet, wherein the filter is inclined relative to the first wall so that filtered fluid is contained in the body between the filter and the outlet.

Fluid container with internal filtration

A fluid distribution system having a first fluid container having a fluid outlet, a second fluid container having a fluid inlet, a fluid line interconnecting the outlet of the first container and the inlet of the second container, an inverted umbrella valve between the fluid line and the inlet, the valve arranged to allow fluid flow from the first container to the second container via the fluid line and a restrictor for restricting the allowed fluid flow through the fluid line.

Fluid distribution system having fluid flow restriction

A system for distributing fluid to a printhead, the system having a printhead a first fluid container and a second fluid container for distributing fluid from the first container to the printhead, the second container having a body for containing the fluid to a predetermined capacity, an inlet connected to the first container, a valve at the inlet, and an outlet connected to the printhead, wherein the valve is operated so that the valve is closed when the body contains fluid at the predetermined capacity and is open when fluid is distributed to the printhead via the outlet.
