A media registration system includes a puller clamp, and a puller track to support the puller clamp. The puller track is to open and close the puller clamp with movement of the puller clamp along the puller track.

Media registration with puller clamp

Some examples include a fuser assembly to operate with a roller including a fuser housing, and an array of fusers disposed in the fuser housing, each fuser including a heating element exposed along a surface of the fuser housing and adjacent to an outer surface of the roller.

Fuser assemblies

In an example, a print system include a component device that is operation in a number of state, a density engine, and a component engine. An example density engine identifies a plane region of a plane where print fluid is to be printed based on data of a print job and determines a density classifier for the plane based on a location of the plane region on the plane. An example component engine causes an adjustment of a component attribute of the component device based on the density classifier.

Density classifiers based on plane regions

An example system includes an advancement mechanism to drive print media into a stacking region, a movable media guide arrangement and a controller. The movable media guide arrangement includes a pair of opposing media guides to receive opposing edges of a print medium therein and a translation mechanism to move the opposing media guides between at least two positions, the at least two positions including a deployed position and a retracted position. The controller is to actuate the translation mechanism to move the opposing media guides into the deployed position when the advancement mechanism transports a print medium into the stacking region and to actuate the translation mechanism to move the opposing media guides to the retracted position to release the print medium.

Media guides

An inkjet printing system may include an inkjet printing device, a print media finishing device, and a conditioner selectively coupled within a housing of the print media finishing device and in alignment with a print media exit of the inkjet printing device where the conditioner includes a number of heated pressure rollers to condition the print media prior to introduction into the print media finishing device.

Inkjet print media conditioner

An example system includes an advancement mechanism to drive print medium into a stacking region, a clamping mechanism, and a controller. The clamping mechanism includes a trailing edge clamping arrangement in a trailing edge portion of the stacking region and at least one downstream clamping arrangement in a downstream portion of the stacking region, the downstream portion being downstream of the trailing edge portion. The controller is to sequentially actuate the trailing edge clamping arrangement and the at least one downstream clamping arrangement when the advancement mechanism transports a print medium into the stacking region.

Sequential clamping

A media tray may include a number of mezzanines to accumulate media as the media is ejected from a printing device and a number of ramps to selectively engage with a leading edge of the media as the media is accumulated based on a plurality of positions of the number of ramps, the number of ramps positionable based on movement of the number of mezzanines. In one example, movement of the number of mezzanines from a first position to a second position may cause the number of ramps to be in a position to selectively engage and disengage with a leading edge of the media.

Media tray with ramp

In one example, a partially dried inkjet media conditioner can include: a print engine that encases a print zone within a housing, and a media path to provide partially dried inkjet media from the print zone to a conditioner within the print engine, wherein the conditioner comprises a heated pressure roller.

Partially dried inkjet media conditioner

A page registration system may include, in an example, a media edge sensor to detect a location of an edge of a print media along a media feed path and in a direction non-parallel to the media feed path and a calibration sensor downstream of the media edge sensor to detect changes in the location of the edge of the print media in the direction non-parallel to the media feed path, and provide calibration data to the page registration system to correct changes in the location of the edge of the print media in the direction non-parallel to the media feed path.

Page registration system

A printing device includes, in one example, a media output system including a mezzanine level including a plurality of media support members, the mezzanine level being intermediate to a floor level and a media output level; wherein the plurality of media support members move orthogonally relative to a print media path so that a number of finishing processes may be performed on print media accumulated on the number of media support members.

Media output system

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

In one example, a system for partially dried inkjet media fusers include a plurality of fusers aligned to receive partially dried inkjet media from a printing device, wherein the plurality of fusers each comprise a top roller and a bottom roller to apply pressure to the received partially dried inkjet media, and a finisher to receive the partially dried inkjet media from the plurality of fusers.

Partially dried inkjet media fusers

A system for presenting media sheets includes a finisher output bin assembly. The finisher output bin assembly includes a translatable output floor, and a guide substrate coupled to the translatable output floor to guide the translatable output floor relative to the guide substrate in at least one coordinate direction. The finisher output bin assembly includes an output structure mechanically coupled to the translatable output floor to drive the translatable output floor relative to the guide substrate.
