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

An apparatus calibrates the optical sensor to calibrate the distance measured by the sensor with the expected distance using a calibration surface at the expected distance.

Sensors calibration

A printing apparatus includes a media bin and a sensor, directed toward the media bin, having a first emitter and a receiver. The printing apparatus further includes a second emitter to emit photons toward the optical sensor, and a controller. The controller determines presence of a print media on the media bin based on a count of photons received from a source other than the first emitter, including the second emitter.

Media bin sensors

A printing apparatus uses a time of flight sensor to determine distance between the sensor and a surface facing the sensor, and uses a reflectivity value to determine presence of print media in a media bin.

According to examples, a printing apparatus may include an output bin that is laterally translatable between a retracted position and an extended position. The printing apparatus may also include a sensor to detect a height of a stack of media on the output bin while the output bin is in the retracted position and a controller. The controller may determine whether the detected height of the stack of media on the output bin exceeds a certain level and in response to a determination that the detected height of the stack of media exceeds the certain level, laterally translate the output bin from the retracted position to the extended position.

Lateral translation of an output bin based on media stack height

According to an example, to eject print media from an image forming apparatus, a variable page feed velocity of a first page of print media exiting a feed zone is detected. An acceleration value and a deceleration value based on the variable page feed velocity of the first page is calculated. The calculated acceleration is applied to a media movement component in the output zone when the entire first page has cleared a media sensor in the front of the output zone, and the deceleration is applied when the tail end of the first page is in a brake zone. In some examples, a second page of print media and a variable page feed velocity of the second page exiting the feed zone is detected, and the media movement component in the output zone is accelerated to match the variable page feed velocity of the second page.
