Abstract: An apparatus is disclosed comprising a print engine in a print zone. A platen opposes the print engine to support print media. The platen includes a plurality of openings in communication with at least one vacuum source. The platen includes a non-vacuum region, comprising a surface devoid of openings in communication with the at least one vacuum source. The non-vacuum region underlies at least a portion of the print zone.

Abstract: An example printing apparatus in accordance with the present disclosure may comprise a platen (10) on which print media may advance and which may comprise a hole (20) that is open towards a print media advance surface and in fluid communication with a vacuum source (40) and with a pressure sensor (50). In implementations of the apparatus a control unit (60) may detect the presence of print media at the hole (20) if the pressure sensor (50) measures an air pressure below a predetermined threshold.

Abstract: The present disclosure discloses print-medium buffering systems that have a set of print-medium-buffer flags (25) which, in one position, maintain a print medium in a guided path (G) as it passes through a print-medium buffer zone. A drive mechanism (30) is provided to move the set of print-medium-buffer flags away from the guided path, to a second position.

Abstract: Print apparatus comprises: a platen to support a print substrate; a print head to apply print agent to a print substrate supported by the platen, the print head being movable relative to the platen to vary a distance therebetween; and a suction device having an inlet, the suction device to draw air from between the print head and the platen and into the inlet. The inlet of the suction device is movable with the print head to vary a clearance between the inlet and the platen.

Abstract: A print target support assembly comprising a print platen structure providing an upper surface to support a print target as the print target passes under a print zone. The print zone is arranged across the surface perpendicular to a direction of print target advance. The surface comprises an inner belt area in the direction of print target advance, the inner belt area bounded on each side by an outer non-belt area. A belt advance mechanism, to advance a belt running across the inner belt area of the surface in the direction of print target advance, to advance the print target under the print zone. A flattening arrangement to flatten the print target onto the surface, under the print zone, across the inner belt area and the outer non-belt areas of the surface.

Abstract: Dryers (300) comprising a first surface (102) and a deflector (302). The first surface comprises at least one opening (104) through which air is forced during use to dry a printed media and the deflector comprises (302) a second surface to change the direction of airflow passing through the at least one opening. The deflector guides the direction of the airflow such that it flows substantially in a direction corresponding to the direction of travel (310) of the printed media.

Abstract: In one example in accordance with the present disclosure a media transport device is described. The device includes a number of drive rollers coupled to a frame. A number of media rollers are also coupled to the frame. The media rollers are in contact with, and rotated by, the number of drive rollers. Media rollers in a first set have a first diameter and media rollers in a second set have a second diameter that is different from the first diameter. The device also includes a number of pinch rollers coupled to the frame. The pinch rollers are in contact with the number of media rollers to form a number of nips through which media passes along a feed path.
