<p>There is provided an air-ventilating device for use in ink-jet printers. Ink is supplied from a reservoir to a plurality of printing jets, each of which communicates with an ink-distributing device. The device has the form of a riser and communicates at substantially its highest point with a ventilating passage of such diameter as to provide a capillary effect. The passage conveniently communicates with an ink-collecting chamber, which in turn communicates with a drain. Such an air-ventilating device enables air to bled from the system with the minimum of effort and with the absence of moving, auxiliary mechanical devices.</p> |
