Abstract: 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.

Abstract: Examples disclosed herein relate to a device including a bail arm. In examples, the bail arm to apply force to a receiving surface of an output bin in a first position. In examples, a motor is to move the bail arm from the first position to a second position in which the bail arm does not apply a force to the receiving surface.

Abstract: In one example in accordance with the present disclosure a system for preventing media misalignment during accumulation. The system includes a number of media clamps having multiple positions to prevent misalignment of an incoming media sheet during accumulation. The number of media clamps are in a raised position after a leading edge of the incoming media sheet has passed over a trailing edge of the stack region. The media clamps are in a clamped position after the leading edge of the incoming media sheet has passed the media clamp.

Abstract: 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.

Abstract: 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.
