    Abstract: Examples include a device for offsetting printing media in a printer input tray. The device comprises a support, a movable arm extended along the media advance direction, a spring for generating a spring force urging the movable arm against the support, and a releasable actuator for compensating the spring force and for selectively offsetting the movable arm away from the support in a plane parallel to a base of the input tray. The movable arm is maintained parallel to the media advance direction during movement of the movable arm.

    Abstract: Disclosed are a printing device, a system and a method for printing medium feed. A device may comprise a support member and multiple rollers. The support member may support a print medium. The multiple rollers may each advance the print medium from the support member in an advance direction. The multiple rollers are arranged in a distributed manner along a width direction. The multiple rollers are operable in a disengage state detached from the print medium and the support member and in an engage state of pressing against the support member such to rest on the print medium or, if the print medium does not extend therebetween, to rest on the support member. The multiple rollers in the engage state are individually movable toward the support member.

    Abstract: Examples relate to adjusting systems to adjust a distance between a print medium support and a printhead. The adjusting system comprises a support structure and a print medium input beam and a print medium output movably coupled to the support structure to support the print medium support. The adjusting system further comprises an input and an output beam driving assembly to respectively move the print medium input and output relative to the support structure between an upper and a lower end including a home position. In addition, the adjusting system comprises an input beam sensor assembly and an output beam sensor assembly comprising a reference sensor and a relative sensor.

    Abstract: A printing system comprises an air-transmissive platen, a vacuum source, a cap and a controller. The vacuum source is configured to draw air through the platen to bias print media towards the platen. The cap is provided on a surface of the platen, between the vacuum source and the platen. The cap is configured to limit air flow through the platen, and comprises a plurality of closable openings provided in a plurality of zones along a length of the cap in a print media advance direction. The controller is configured to selectively open or close the openings of each of the plurality of zones to permit airflow through a portion of the platen overlain by print media and limit airflow through a portion of the platen not overlain by print media.
