Abstract
A system for priming and de-priming a printhead, the system having a fluid container fluidically interconnected with the printhead via a closed fluid flow loop, a gas inlet on the closed loop and a valve on the closed loop for selectively allowing gas to enter the closed loop via the gas inlet, and a pump on the closed loop, wherein the pump is operational to draw fluid from the container in a first direction around the closed loop to prime the printhead with fluid from the container, and the vent is operational to cause fluid in the closed loop and the printhead to de-prime to the container in a second direction around the closed loop.
