    Abstract: In one example, a method of controlling a printing system is described, the method comprising activating a driver to advance a conveyor belt in a plurality of sub-turns. For each of the plurality of sub-turns, a first parameter associated with movement of the conveyor belt is determined, based on data obtained from the driver. For each of the plurality of sub-turns, a second parameter associated with movement of the conveyor belt is also determined, based on data obtained from an optical sensor. A per-sub-turn slippage parameter is calculated for each of the plurality of sub-turns, based on any difference between the first parameter and the second parameter. The method further comprises calculating a slippage metric based on the per-sub-turn slippage parameters for the plurality of sub-turns, and causing outputting of a conveyor belt tension adjustment indication.

    Abstract: A tensioner device for use with a printing device is described which is to hold an end of a print target holder sheet in a substantially planar configuration across a platen of a printing device. The tensioner device can be fixed to a frame attachable to a platen of a printing device. The tensioner device has a first surface, and the frame has a second surface corresponding to the first surface. The first surface is formed to slide along the second surface in a first direction having an oblique angle with respect to a plane of the print target holder sheet. A fixing mechanism is also described which allows the first surface to be fixed to the second surface at different positions along the first direction. An apparatus including the tensioner device and the frame is also described. A system including a printer, a platen, tensioner devices and frames is also described.

    Abstract: A print substrate transport system comprises a print substrate supply mechanism and a tensioner. The print substrate supply mechanism is configured to advance print substrate to a printing zone in a discontinuous motion. The tensioner is provided downstream of the print printing zone and is configured to guide a path of the print substrate from the printing zone to a post-processing zone, to control tension in the print substrate in the post-processing zone, and to convert the discontinuous motion of the substrate to continuous motion. A print substrate transport method comprises supplying a print substrate to a printing zone in a discontinuous motion, controlling a tension of the print substrate on a path downstream of the printing zone and converting the motion of the substrate from the discontinuous motion to a continuous motion.
