Publication number: 20140263701Abstract: Example fluidic devices and methods are described. An example device includes a throughput chamber, an inlet to guide liquid in the throughput chamber and an outlet to guide liquid out of the throughput chamber. The example device also includes a rib that protrudes from a wall of the throughput chamber.

Publication number: 20140132656Abstract: In one example, a liquid dispensing device includes a printhead assembly having a liquid port through which liquid may move between a removable liquid container and the printhead assembly and an air port through which air may flow to and from the container. A pressure source is operatively connected to the air port to pressurize the container to push liquid from the container through the liquid port into the printhead assembly. A vent is operatively connected to the air port to vent the pressurized container to draw froth from the printhead assembly through the liquid port into the container. In another example, a method for priming a printhead assembly includes pushing liquid from a container into the printhead assembly through a liquid port and then pulling froth from the printhead assembly into the container through the liquid port.Type: ApplicationFiled: January 22, 2014Publication date: May 15, 2014Inventors: Curt Gonzales, Jeana M.
