Abstract: A vacuum system for a printing apparatus comprises a structural member. The structural member comprises a fluid conduit to be connected to a vacuum source. The vacuum system comprises a coupling. The coupling comprises a first end and a second end defining a fluid passage therebetween. The coupling is attached to the structural member at its first end thereby connecting the fluid passage of the coupling to the fluid conduit of the structural member. The second end of the coupling comprises a resiliently deformable material. The second end is to connect to a vacuum chamber of a print unit.

Abstract: A sensor support, as well as a platen and printer for use with the sensor support. The sensor support comprising a first section and a second section. The first section is capable of receiving a sensor. The first section and the second section are associated together such that there is at least a degree of freedom of movement of the first section relative to the second section. The sensor support further comprises biasing means to urge the first section away from the second section.

Abstract: A platen having a first dimension and a second dimension. The first dimension is perpendicular to the second dimension. The platen has two opposing long edges along the first dimension and two opposing short edges along the second dimension. The platen has a higher stiffness in the direction of the second dimension than in the direction of the first dimension. Each of the two opposing long edges has at least three biased attaching members spaced therealong to bias the platen towards a structural support.

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: A system to transport a medium comprises a medium carrier, a negative pressure device, a vacuum chamber and a flow control device. The medium carrier is to carry the medium on a first side. The negative pressure device is to generate a negative pressure that is below an ambient pressure. The vacuum chamber is disposed on a second side of the medium carrier opposite to the first side and fluidly coupled to the negative pressure device. The flow control device is to manipulate a fluid flow from the vacuum chamber towards the negative pressure device. The flow control device is operated in response to the medium carrier changing its operational state.
