Abstract: A height adjustment apparatus for a print carriage comprises a support for supporting the print carriage and a moving mechanism. The support has an upper support surface configured to slidingly engage a surface of the print carriage. The height of the support surface in a first direction increases in a second direction, perpendicular to the first direction. The moving mechanism is configured to move the support in the second direction, wherein when the support is moved in the second direction, the print carriage surface is configured to slide relative to the support surface to move the print carriage in the first direction.

Abstract: A system to determine a relative position between a moveable part and a working surface is disclosed. The system comprises a controller to control a light emitter from an array of light emitters to emit a signal at a setting, the setting being indicative of a position associated with the light emitter. The controller further to receive a signal from the sensor indicative of the setting. The controller also to determine the relative position between a moveable part and the working surface based on the signal.

Abstract: Methods and apparatus for sublimation printing are described, in which a printed textile medium with a sublimating printing substance on a print side is positioned in correspondence with a heating device, with the print side facing away from the heating device, and a negative pressure is caused on the print side of the textile medium, to cause heated air to flow through the printed textile medium thereby sublimating the sublimating printing substance on the printed textile medium.
