An example system may comprise a media support including a wall and a base and a restraining extension extending in a first direction to constrain print media, when present, to a space below the restraining extension.

Restraining extensions

A finisher apparatus includes an actuator to control a component of the finisher apparatus to perform a finishing operation on a print medium. A sensor is provided to sense the print medium in a print-medium path in the finisher apparatus. A processor is coupled to the actuator and the sensor. The processor is to execute instructions. The instructions are to actuate the actuator to eject the print medium from the print-medium path in response to a signal from the sensor indicative of a jam of the print medium in the finisher apparatus.

Finishers to eject jammed print media

Example printer finishing apparatus are described herein. An example printer disclosed herein includes an alignment guide, a track to align a sheet relative to the alignment guide, a clamp to move between a raised position and a lowered position relative to the sheet, and a force applicator coupled to the clamp. The force applicator is to cause the sheet to engage the alignment guide when the clamp is in the lowered position.

Printer finishing apparatus

Example implementations relate to print media stacks. In some examples, a device may include a sheet channel to guide a sheet of print media within the sheet channel above and separated in a vertical direction from a stack of printed media when the sheet of print media exits a print path of a printer. The device may include a plurality of clamps to control alignment of the sheet of print media on the stack of printed media when the sheet channel moves outboard from the sheet of print media to allow the sheet of print media to fall onto the stack of printed media, wherein the plurality of clamps sequentially pin the sheet of print media to the stack of printed media from a middle portion of the sheet of print media outward.

Print media alignments

An example damp can include a first post, a first clamping element rotatably oupled to the first post, a second post separate from the first post, a second clamping lement rotatably coupled to the second post, and a biasing device that couples the first lamping element to the second damping element.

Clamps having rotatable clamping elements

A finisher apparatus includes an accumulator to register a print medium of a print job in preparation for a finishing operation, memory to store an attribute of the print job, and a processor coupled to the accumulator and the memory. The processor is to execute instructions. The instructions are to control the accumulator based on the attribute of the print job.

Print media accumulators controlled by print job attributes

Example described herein relate to a print shoes. For instance, a print shoe can include a body including a first surface, a first arm extending from the first surface and including a first mounting mechanism to couple to a spring, and a second arm extending from the first surface in a position substantially coplanar with the first arm, where the second arm includes a second mounting mechanism to couple to the spring and dispose the first arm a distance away from the second arm when coupled to the spring.

Print shoes

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

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 example system includes a stacking portion having a leading edge portion and a trailing edge portion, the stacking portion being to receive print media transported into the stacking portion in a direction from the trailing edge portion to the leading edge portion; a bar clamp extending longitudinally in the direction of transport of the print media; and a driver arrangement to selectively extend the bar clamp onto the stacking portion and to retract the bar clamp away from the stacking portion.

Bar clamp for media

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

A media registration system including an accumulation region and a transport track to receive and transport each media sheet of a series of media sheets forming a media job in a transport direction from an intake end to a registration end proximate to the accumulation region, and to stack the media sheets of the media job in the accumulation region to form a job stack. A translator adjusts a position of the registration end of the transport track in a direction lateral to the transport direction for each sheet to align edges of each sheet of the job stack in the lateral direction. A media sensor indicates a position of each sheet along the media path to facilitate a controller to determine an accumulation status of the job stack.

Media registration system with media sensing

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

In one example in accordance with the present disclosure an object transportation device is described. The device includes a continuous belt having an inner surface and an outer surface. The inner surface interacts with a belt transport system. The device also includes a number of attachment devices disposed on the outer surface of the belt. An object attaches to the belt via an attachment device. An attachment device includes two angled protrusions extending from the outer surface from a common joint.
