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 printing apparatus is disclosed herein. The apparatus comprises a platen to hold a media thereon, the media moveable along a media path direction; a displacement mechanism to move the media over the platen and along the media path direction; a media advancement prediction based on an operational parameter a media path direction; a displacement mechanism to move the of the displacement mechanism; determine a read media advancement corresponding to the media advancement prediction; determine a sensor reading failure based on the media advancement prediction and the read media advancement; determine that the media advanced a distance corresponding to the media advancement prediction if the sensor reading failure is detected; determine that the media advanced a distance corresponding to the read media advancement if the sensor reading failure is not detected; and to adjust the position of the media by controlling the displacement mechanism to move the media based on the determined media advanced distance.

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: According to an example, a method to wind media in an output roller downstream a media advance engine comprises advancing a medium for a determined medium length, collecting a first portion of the determined medium length at a first speed by rotating the output roller in a winding direction, and collecting a second portion of the determined medium length by rotating the output roller in a winding direction at a second speed, wherein the first speed is greater than the second speed.

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: In an example, an autonomous vehicle comprises first and second sensors, wherein each of the first and second sensors is to acquire first and second position measurements for the autonomous vehicle. The autonomous vehicle may comprise a processor to compare the first and second position measurements and when the first and second position measurements are in agreement, determine a position of the autonomous vehicle by selecting the first position measurement, and when the first and second position measurements are not in agreement, determine the position of the autonomous vehicle by filtering the first and second position measurements with a stochastic filter.
