ABSTRACT:
A printhead assembly is described including multiple printheads, a manifold and multiple inlet tubes. The printheads each include: a fluid inlet to receive fluid into the printhead; and a set of one or more nozzles to deposit fluid on a substrate. The manifold is connected to the printheads and includes: a fluid inlet duct configured to receive fluid for delivery to the printheads; multiple fluid inlet channels for connecting the fluid inlet duct to the printheads; and multiple fluid inlet valves configured to control a flow of fluid from the fluid inlet duct to each of the fluid inlet channels. The inlet tubes each have a proximal end integral to either the manifold or one of the printheads, and a distal end connected to either the manifold or said printhead with a single fluid-tight connection.
