A fluid level sensing system includes: a sensor electrode to extend into a fluid reservoir, the sensor electrode including (i) a first segment of a first material having a first conductivity, and (ii) a second segment of a second material having a second conductivity; and a controller connected to the sensor electrode, to: detect a response from the sensor electrode to an input applied to the fluid reservoir; and determine, based on the response, which of the first and second segments are in contact with fluid in the fluid reservoir.

Composite electrode fluid level sensing

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

An example method includes maintaining, by a processing resource associated with a finisher communicatively coupled to a printer, an interpage delay table, the interpage delay table storing an interpage delay value for each of a plurality of page attribute combinations. The method further includes processing, by the finisher, a job based at least in part on a particular interpage delay value stored in the interpage delay table for an identified page attribute combination.

Adaptive interpage delays

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

In some examples, a gimbaled monoclamp can include a housing including a first opening, a second opening, and a pivot point, a clamp disposed at least partially in the housing and including a first pad and a second pad to extend through the first opening and the second opening, respectively, and a pin extending through an opening in the clamp into the pivot point to couple the clamp to the housing in a gimbaled manner.

Gimbaled monoclamps

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

In one example, a media puller device can include a snowplow device coupled to a first end of a hinge, a leading end of the media puller device coupled to a second end of the hinge, and a tension device coupled between the snowplow device and the media puller device.

Media puller barrier devices

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

A system may include a finishing device to receive a print job. The print job may move about a first axis of the finishing device. The system may further include a stapling device contained within the finishing device. The stapling device to move about a second axis of the finishing device, and the second axis may be perpendicular to the first axis. A sensor may be located on the stapling device to identify a first edge of the print job. The first edge of the print job may be a leading edge of the print job as the print job moves about the first axis.

Stapling sensors to indicate movement of a stapling device

A media registration system including a track to transport media in a transport direction from an intake end to a registration end, and a pivot shaft. A translator to register media in a lateral direction to the transport direction includes a translation element operatively coupled to the track and moveable along a translation axis in the lateral direction, and a driver to drive the translation element a translation distance along the translation axis to rotate the track about the pivot shaft to move the registration end a selected registration distance in the lateral direction, the translation distance proportional to the selected registration distance.

Media registration system with lateral registration

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

A cable slack controller may include a deflector coupled to a movable carriage device; at least one end of a cable coupled to the carriage device; and an engagement tab formed with the cable wherein the engagement tab engages a notch defined in a portion of a channel on which the movable carriage device translates across.
