Abstract: A printing device is provided which includes ink-dispensing structure which carries a printhead with a leading edge, and which moves in a printing sweep downstream across a printzone, a fairing structure, and a mounting structure which supports the fairing structure for movement with the printhead downstream from the leading edge of the printhead in a position configured to reduce aerodynamic turbulence associated with the leading edge of the printhead during movement of the printhead downstream across the printzone.

Abstract: An inkjet carriage for holding an inkjet pen includes an airflow reducing member configured and positioned to at least partially block airflow between an inkjet ejection nozzle of a pen on the carriage and an object to be printed upon during carriage movement.

Abstract: In an implementation of printing mechanism hinged printbar assembly, a hinged printbar assembly pivots about a hinge between a print position and a service position. Print modules coupled to the hinged printbar assembly each have one or more printheads and the printheads of the print modules collectively span a width of a print media when the hinged printbar assembly is in the print position. A wiper assembly services the printheads on the hinged printbar assembly and includes printhead caps to cover the printheads on the hinged printbar assembly.

Abstract: Disclosed herein is a method of placing fluid droplets onto an object. The method includes moving a fluid ejection device in a first direction, reducing air flow between the fluid ejection device and the object with a member leading the fluid ejection device, and ejecting the fluid droplets onto the object.

Abstract: A print unit, such as an inkjet printing mechanism, includes a hinged printbar assembly that has print modules with one or more printheads to deposit an imaging medium, such as ink, onto a print media. The one or more printheads of the print modules collectively span a width of a print media when the hinged printbar assembly is in a print position. The hinged printbar assembly pivots about a hinge from the print position to a service position to provide service access to the one or more printheads of the print modules. The print unit also includes a wiper assembly having one or more wipers that correspond to the one or more printheads, such that when the wiper assembly and the print module are positioned in the service position, the wipers clean the printheads.

Abstract: A print unit, such as an inkjet printing mechanism, includes a printbar assembly that has print modules with one or more printheads that collectively span a print region corresponding to a width of a print media and deposit an imaging medium, such as ink, onto the print media. Wiper assemblies move from a print position to a service position in the print region to service the one or more printheads of the print modules. A wiper assembly has one or more wipers that correspond to the one or more printheads, such that when the wiper assembly and the print module are positioned in the service position, the wipers clean the printheads. The wiper assembly also has one or more printhead caps that cover the one or more printheads on the print modules.
