In one example in accordance with the present disclosure a print duplexing assembly is described. The assembly includes a duplexing device to facilitate printing on both sides of a print media. The assembly also includes a platen coupled to the duplexing device to guide the print media along a feed path as it is being printed on. The platen and the duplexing device are selectively removable from a printing device in which they are installed.

According to examples, an apparatus may include a back panel to absorb energy and an energy emitter to supply energy onto a build material layer. The energy emitter may include an energy emitting element and an outer tube. In addition, a reflective element may be provided on a portion of the outer tube facing the back panel to direct energy away from the back panel. The apparatus may also include a transparent panel, in which energy from the energy emitter may be emitted through the transparent panel and onto the build material layer.

Energy emitting apparatuses for build material layers

An example apparatus includes a media receiving portion having a leading edge receiving region and a trailing edge receiving region for receiving media traveling onto the media receiving portion in a direction from the trailing edge receiving portion the leading edge receiving portion. The example apparatus further includes a leading edge stop coupled to the media receiving portion at the leading edge receiving portion. The leading edge stop is resiliently coupled to the media receiving portion to bias against movement of the leading edge stop from a resting position.

Media stops

In one example, a bail system for a sheet media tray includes a bail to apply a force to a sheet in the tray, a bias mechanism to counter the force of the bail on the sheet, and a control mechanism to control the degree to which the bias mechanism counters the force of the bail on the sheet.

Bail control for sheet media

Examples disclosed herein relate to a device including a bail arm to rotate and oscillate. Examples include a shaft coupled above an output tray; and a bail arm to rotate and oscillate about a central axis of the shaft. In examples, the bail arm is to provide a downward force on the output tray.

Bail arm to rotate and oscillate

A media handling system is disclosed herein. An example includes media path, a transport assembly to move print media through the media path, a processor, and a non-transitory storage medium including instructions that cause the processor to control the transport assembly to: move a first medium and second through the media path, overlap a trailing portion of the first medium and a leading portion of the second medium within the media path, overlap a leading portion of the first medium and a trailing portion of the second medium within the media path, and overlap the trailing portion of the first medium and the leading portion of the second medium during a time that the leading portion of the first medium and the trailing portion of the second medium is also overlapped. A method of media handling is also disclosed herein as is a non-transitory storage medium.

Media handling system

Printers and duplexers are described herein. An example duplexer for a printer includes a waste ink roller movable between a concealed region and a receiving region.

Printers and duplexers for printers

Printers and duplexers are described herein. An example duplexer for a printer includes a print substrate path to guide a print substrate and a chamber to collect a fluid.

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.

Aerodynamic fairing structure for inkjet printing

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.

Apparatus and method for placing fluid droplets onto an object

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.

Printing mechanism hinged printbar assembly

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.

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.
