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.

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.

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

In one example, an apparatus includes a plate configured to pivot about a pivot point, a pulley coupled to a first planar side of the plate and configured to rotate a belt, a motor coupled to the first planar side of the plate and configured to drive the pulley, and a torsion spring coupled to a second planar side of the plate that is opposite the first planar side and configured to apply tension to the belt.

A media transport system, includes a transport path, a drive gear at one end of the transport path, a driven gear at an opposite end of the transport path, an endless loop transmission element engaged with the drive gear and the driven gear, a media clamp secured to the endless loop transmission element, and a one-way clutch coupled with the driven gear. The endless loop transmission element is to rotate in one direction to move the media clamp and transport media from the one end of the transport path toward the opposite end of the transport path, and the one-way clutch is to allow rotation of the driven gear in the one direction and resist rotation of the driven gear in an opposite direction.

Media transport

According to an example, a scanner apparatus may include a housing, a scan panel positioned on the housing and a lid rotatably mounted to the housing. The lid may be moved between a closed position and an open position, in which in the closed position, the lid covers the scan panel and in the open position, the lid is extended away from the scan panel. The scanner apparatus may also include an optical sensor to detect media placed on the scan panel and a media engine to determine whether the optical sensor has detected a media on the scan panel while the lid is in the open position.
