Abstract
In one example, a liquid delivery system for an inkjet type dispenser includes a reservoir to hold liquid, a chamber downstream from the reservoir, a one-way valve to allow the flow of liquid from the reservoir into the chamber and to block the flow of liquid from the chamber back into the reservoir, and a manually actuated pump to pull liquid from the reservoir into the chamber through the valve and to push liquid from the chamber toward a printhead.
