摘要:
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.
摘要:
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.
摘要:
A method of priming a media width printhead, the method having controlling operation of the printhead, with a controller of a printing system having the printhead, to draw fluid in a first direction around a closed fluid flow loop from a fluid container to the printhead and controlling operation of a pump on the closed loop, with the controller, to draw fluid from the container in an opposite, second direction around the closed loop.
摘要:
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 substantially parallel to, and spaced from, a second wall of the body wherein the second wall adjoins the first wall with the outlet in the space between the filter and the second wall so that the contained fluid passes through the filter before exiting the outlet and the second wall declines from the adjoined first wall when the container is disposed with the filter above the second wall.
摘要:
A fluid distribution system for a printhead, the system having a plurality of fluid containers fluidically interconnected with the printhead via a respective plurality of closed fluid flow loops, a plurality of bypass fluid paths bypassing the printhead, each bypass path being associated with a respective one of the closed loops and a plurality of gas vents, each gas vent being associated with a respective one of the closed loops and a multi-channel four-way valve for selectively allowing fluid flow along each closed loop via the printhead and the bypass paths and venting of gas in each closed loop via the gas vents.

摘要:
A printing system having a fluid container, a media width printhead having a first fluid port at one longitudinal end of the media width and a second fluid port at the other longitudinal end of the media width, a first fluid path interconnecting the container and the first fluid port of the printhead, a second fluid path interconnecting the container and the second fluid port of the printhead, a third fluid path interconnecting the first and second paths, wherein the first, second and third paths are configured so that fluid from the container flows between the first and second paths via the printhead and via the third fluid path.
摘要:
A method of controlling fluid pressure at a printhead with a fluid distribution arrangement, the method having providing the fluid distribution arrangement with a first fluid container, a fluid connector for connection to a fluid input of the printhead, and a second fluid container connected between the first container and the connector for delivering fluid from the first container to the connector and locating the second container relative to the first container and the connector so that a fluid pressure difference between fluid contained within the second container and fluid at the connector is independent of the amount of fluid contained within the first container.
摘要:
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.
